MC9328MX21SCVKR2

MC9328MX21SCVKR2 - i.MX21 32-Bit 266MHz ARM9 MPU | NXP

The NXP MC9328MX21SCVKR2 is an ARM926EJ-S-based 32-bit applications microprocessor from the i.MX21 family, operating at up to 266 MHz and housed in a 289-ball LFBGA (MAPBGA) package measuring 14x14 mm. The SC suffix indicates the i.MX21S derivative, an optimized variant for designs that require ARM926EJ-S CPU performance but do not need the high-resolution video/graphics accelerators found on the i.MX21 full part. An ARM926EJ-S microprocessor is a 32-bit RISC core that combines the ARM9 instruction set with a five-stage pipeline, an MMU for virtual memory, and tightly-coupled AMBA peripherals. As an applications processor (AP) within the broader system-on-chip (SoC) taxonomy, the i.MX21S integrates CPU, memory controller, and I/O onto a single die - one tier above a bare microcontroller and a generation ahead of older ARM7TDMI designs in performance-per-mW. It is the SC variant of the i.MX21 family, lacking the video/graphics engines of the full i.MX21 (no LCD controller, no CMOS sensor interface, no MPEG-4 hardware) - making it a cost-down choice for industrial HMI, handheld terminals, and embedded control loops. Key features include 192 GPIO lines, an external oscillator input, ARM926EJ-S core with DSP extensions, and a wide operating voltage range typical of i.MX21 silicon. The 289-LFBGA package is a Micro-Profile Ball Grid Array with 0.8 mm pitch designed for high-density four-layer PCBs; its 14x14 mm footprint balances routability against board area. The R2 suffix denotes the tape-and-reel packaging option for high-volume assembly. Architecturally, the i.MX21S integrates the ARM926EJ-S core, 128 KB of internal SRAM, a multi-mode memory controller for SDRAM/Flash/NOR/NAND, USB 2.0 full-speed, three UARTs, I2C, SPI, and PWM/timer blocks. DSP-style ARM instructions (enhanced DSP extensions) accelerate signal-processing tasks that would otherwise require a dedicated DSP coprocessor. Typical applications include industrial HMI panels, portable data terminals, handheld barcode scanners, embedded web terminals, and remote-control point-of-sale terminals. The 266 MHz ARM9 throughput is well-matched to mid-2000s UI stacks such as embedded Linux or WinCE 5.0/6.0. Designers choose the i.MX21S when they need CPU performance but the LCD/Camera peripherals of the full i.MX21 would consume cost and board area without being used. When designing, ensure the four-layer PCB stack-up supports the 0.8 mm BGA escape routing and that decoupling is placed adjacent to each BGA quadrant. The 192 GPIO lines enable flexible peripheral mapping, but unused pins should be left as No-Connects rather than grounded to avoid internal pull-up contention.

MC9328MX21SVK - i.MX21S ARM9 266MHz MPU, 289-LFBGA | NXP
MC9328MX21SVK

MC9328MX21SVK - i.MX21S ARM9 266MHz MPU, 289-LFBGA | NXP

The NXP MC9328MX21SVK is an i.MX21S applications processor built around the ARM926EJ-S core running at up to 266 MHz, housed in a 289-ball 14x14 mm LFBGA (MAPBGA) package. The i.MX21S is a derivative of the i.MX21 multimedia processor, retaining its expansion slots and connectivity peripherals while omitting the highest-resolution video/graphics paths, trading those for lower cost and power. The device is ROMless and targets designs that bring their own boot media (NAND/NOR flash), RAM density, and operating system, with 192 GPIO pins available for system integration. An applications processor is a high-integration system-on-chip that combines a CPU, memory controllers, display and connectivity peripherals, and dedicated hardware accelerators on a single die. The i.MX21S sits inside the broader hierarchy of embedded multimedia processors (ARM9-class MPU) and is commonly used as the host CPU for human-machine interfaces, industrial HMI, and connected portable terminals where Linux or WinCE/WinMX software environments are deployed. Key features include ARM926EJ-S 32-bit RISC core with MMU, on-chip LCD controller, USB On-The-Go controller, 1-Wire interface, CMOS sensor interface, and multiple synchronous serial interfaces (SSI/I2S/SPI). The 289-LFBGA package exposes a 32-bit external bus and SDRAM controller, plus integrated peripherals for system bring-up including timers, DMA, real-time clock, and interrupt controller. Per the NXP datasheet on nxp.com, the part is qualified for commercial temperature ranges and is supplied in tray packaging. Typical applications include industrial human-machine interface panels, portable data terminals, point-of-sale terminals, medical patient monitoring displays, and low-cost web-pad style appliances. Designers pair the i.MX21S with external SDRAM and NAND/NOR flash, using its LCD controller to drive QVGA/VGA TFT panels and its USB OTG port to connect to peripherals or to a host PC. The 192 GPIO count and rich serial connectivity make it straightforward to add Ethernet PHYs, CAN transceivers, and audio codecs without an external companion MCU. A key design consideration is that this part is a legacy i.MX21 family member and has been flagged End-of-Life by NXP; production designs should evaluate current i.MX RT or i.MX 6/7/8 successors. PCB layout for the 289-LFBGA demands 0.8 mm pitch fan-out, four-layer stack-up with continuous reference planes, and matched-length SDRAM traces to meet timing on the 16-bit external memory bus.

The NXP MC9328MX21VK is an i.MX21 family applications processor integrating an ARM926EJ-S core running at speeds up to 266 MHz with Smart Speed Switch technology, housed in a 289-ball MAP-BGA package. It combines 16 KB instruction cache, 16 KB data cache, and a vector floating-point coprocessor (VFP) co-tencel executes the ARMv5TEJ instruction set for low-power, high-performance multimedia processing. The part is fabricated on a 0.13 micron CMOS process and is targeted at handheld, portable, and embedded multimedia products. An applications processor is a system-on-chip (SoC) class integrated circuit that integrates a CPU core, memory controllers, and a rich set of peripherals into a single die to run user-facing applications rather than system housekeeping. Within the i.MX hierarchy, the i.MX21 sits between the i.MXL and i.MX1 legacy parts and the i.MX27 / i.MX31 successors, optimized for power-sensitive portable designs where battery life, LCD driving, and basic multimedia playback are essential. Key features include a 16/18-bit color LCD controller with up to SVGA resolution, USB On-The-Go (two-host port), 1-Wire interface, CMOS sensor interface, MPEG-4 and H.263 encode/decode hardware acceleration up to CIF 30 fps, and on-chip peripherals such as I2C, SPI, UART, SSI, and an SDRAM/DDR memory controller. The device supports both Little-Endian and Big-Endian byte ordering and offers a JTAG boundary-scan interface for production test. Architecturally, the i.MX21 employs a Harvard-style cache with separate I/D paths feeding an ARMv5TEJ integer pipeline, plus an AHB system bus that ties together the LCD controller, USB OTG, image-processing accelerator, and external memory interface. The on-chip MPEG-4 / H.263 accelerator offloads video encode from the ARM core, allowing CIF-resolution recording at 30 fps without CPU saturation. Typical applications include PDAs and handheld terminals, GPS personal navigation devices, industrial HMI panels, MP3/MP4 portable media players, two-way video intercoms, and smart-meter readout terminals. The combination of LCD controller and OTG USB makes it well suited to devices that need a small touch-screen UI plus plug-in mass storage. When designing with this part, allocate at least four PCB layers for the BGA breakout, place decoupling capacitors on the inner layers directly under the package, and keep the 14 mm x 14 mm BGA thermal pad soldered to a continuous ground pour for the 1.18 mm body. The legacy status of the i.MX21 line means designers should evaluate the i.MX27 or i.MX31 for new programs while still sourcing this part for maintenance of installed fleets. This page synthesizes distributor stock, same-package drop-in variants within the i.MX21 family, and practical BGA-layout guidance not found in the original Motorola / Freescale datasheet, giving engineers a single reference for both new design and field-replacement decisions.

MC9328MXLCVP15 - i.MXL ARM9 MPU 150MHz 225-MAPBGA | NXP
MC9328MXLCVP15

MC9328MXLCVP15 - i.MXL ARM9 MPU 150MHz 225-MAPBGA | NXP

The NXP MC9328MXLCVP15 is an i.MXL applications processor built around an ARM920T core running at 150 MHz, packaged in a 225-ball MAPBGA (13x13 mm) for industrial and consumer embedded designs. As a member of the Freescale (now NXP) i.MX family, it integrates an ARM9TDMI-compatible core, MMU, LCD controller, USB, and memory interfaces for handheld and HMI products. An MPU (Microprocessor Unit) is a CPU-centric SoC that orchestrates system peripherals without integrating user-level flash; the i.MXL sits at the entry of the i.MX application-processor hierarchy, which scales upward to i.MX1, i.MX21, and modern i.MX8. The i.MXL targets cost-sensitive human-machine interfaces where deterministic ARM9 performance, integrated LCD support, and a mature toolchain outweigh the need for Cortex-class DSP or SIMD engines. Key features of the MC9328MXLCVP15 include a 16 KB instruction cache and 16 KB data cache, a 32-bit SDRAM controller supporting up to 128 MB external memory, integrated LCD controller up to VGA resolution, USB 1.1 full-speed device, and an operating voltage of 1.8 V core with 3.3 V I/O. The 225-ball MAPBGA exposes the full peripheral set including two UARTs, two SPIs, two I2C, and a 16-bit external bus. Architecturally, the i.MXL pairs an ARM920T Harvard core with a peripheral bus matrix that lets DMA and the LCD controller operate in parallel with CPU fetches, eliminating most video-tearing artefacts. The 150 MHz clock is generated internally from an external crystal, and the integrated phase-locked loop supplies both the core and the peripheral domains. This architecture positions the i.MXL between simple ARM7 microcontrollers and more complex Cortex-A8 application processors. Typical applications include industrial HMI panels, handheld data terminals, GPS personal navigation devices, point-of-sale terminals, and low-cost portable medical instrumentation. Designers choose the i.MXL when a 32-bit MMU-capable core is required at price points that Cortex-M parts cannot meet for multimedia workloads, but Cortex-A silicon is still over-spec. When designing with the MC9328MXLCVP15, pay close attention to PCB routing of the MAPBGA escape and decoupling of the analog PLL supply. Because the part is now in NXP's End-of-Life pipeline, long-life designs should validate last-time-buy windows against Rochester Electronics inventory or qualified aftermarket stock. This page synthesizes distributor pricing, verified pin-compatible alternatives, and practical design considerations not found in the original Freescale datasheet, giving engineers a one-stop reference for sustaining legacy i.MXL designs.

MC9328MXLDVM15-FR

MC9328MXLDVM15-FR - i.MXL ARM920T 200MHz Microprocessor | NXP

The NXP (formerly Freescale) MC9328MXLDVM15-FR is a high-integration ARM920T-based applications microprocessor running at 200 MHz, housed in a 256-ball LFBGA (MAP) package and qualified for the industrial temperature range. It combines an ARM9TDMI core with the i.MXL system-on-chip peripheral set, making it a foundational building block for embedded systems where deterministic control and rich connectivity are required. The -FR suffix denotes a factory-reel packing option; the silicon is identical to the standard MC9328MXLDVM15. A microprocessor is the central processing unit of an embedded computing system, executing instruction streams fetched from memory and coordinating peripherals through on-chip interconnect. The ARM920T core implements the 32-bit ARM instruction set with a five-stage pipeline, MMU, and separate 16 KB instruction and 16 KB data caches. The i.MXL family (microprocessor -> applications processor -> system-on-chip -> semiconductor) targets cost-sensitive industrial, HMI, and point-of-sale designs that need more compute than an MCU but do not require the cost of an applications processor. Key features include 200 MHz core frequency, 16 KB / 16 KB L1 caches, integrated LCD controller with TFT support, USB 1.1 device and host (with transceiver), 10/100 Ethernet MAC, PCM/I2S audio codec interface, SD/MMC memory card host, three UARTs, two SPIs, two I2C ports, PWM timers, and a real-time clock. Memory expansion is handled through an SDRAM controller, NAND flash controller, and external bus interface. Architecture-wise, the i.MXL is built on a 0.18 um CMOS process and uses an AHB/APB layered bus matrix so the ARM core, DMA channels, and peripherals can operate concurrently. The integrated peripherals are mapped to dedicated interrupt vectors with a configurable priority scheme, allowing deterministic response for real-time control loops without off-chip logic. Typical applications include industrial human-machine interfaces, point-of-sale terminals, portable data collectors, smart-home gateways, and low-end multimedia consoles. The wide peripheral set keeps the bill of materials small: a single i.MXL plus SDRAM and NAND replaces a CPU, graphics controller, USB transceiver, and Ethernet PHY in many designs. Design consideration: the LFBGA-256 package requires careful PCB layout with matched-length traces to the SDRAM controller; bypassing must follow the manufacturer reference design and the device is sensitive to supply-rail sequencing between PLL and core voltage domains.

MC9328MXLDVP15

MC9328MXLDVP15 - ARM920T i.MXL 150MHz MPU | NXP | MAPBGA-225

The NXP MC9328MXLDVP15 (i.MXL) is an ARM920T-based 32-bit applications microprocessor for portable and embedded multimedia devices. It integrates an ARM920T core running at up to 150 MHz, a USB device controller, an LCD controller, and an MMC/SD host controller, all packed into a 225-ball MAPBGA (13x13) package. As a member of the MX family, the i.MXL targets power-constrained handheld applications where integration reduces bill of materials and PCB area. An applications processor (AP) is a system-on-chip (SoC) class microprocessor designed to run a full operating system and rich user interfaces, as opposed to a microcontroller (MCU) which typically runs bare-metal or RTOS code. The i.MXL belongs to the MX family of applications processors, itself descended from the Dragonball line acquired by Motorola/Freescale and now NXP. Its ARM920T core places it in the ARM9 family, an architecture that introduced the Harvard cache arrangement and MMU that enable full Linux and Windows CE support, sitting above ARM7 controllers and below the more capable ARM11 and Cortex-A cores used in later i.MX generations. Key features of the MC9328MXLDVP15 include a maximum core clock of 150 MHz, an integrated 16-bit color LCD controller with touchscreen interface, USB 1.1 device port, MMC/SD card host bus, and a CSI (CMOS sensor interface) for camera input. The chip integrates dual 16KB instruction and data caches plus 16KB SRAM. Memory expansion is provided through SDRAM, NAND flash, and PC Card / CompactFlash controllers, eliminating external memory glue logic in many designs. Architecturally the i.MXL pairs the ARM920T core with a multi-master AHB-Lite system bus and a peripheral bus for slower on-chip modules. Hardware accelerators and DMA channels offload memory transfers from the core, and the integrated PLL generates all internal clocks from a single external reference. Process technology is a low-leakage CMOS tailored for battery-powered operation, with deep sleep and doze modes managed through the system control module. Typical applications include early-generation PDAs and smart handhelds, industrial HMI panels, portable data terminals, GPS personal navigation devices, and point-of-sale terminals. The wide peripheral mix also suits simple kiosk controllers, in-vehicle infotainment prototypes, and ZigBee/Bluetooth base stations where on-chip memory and host controllers reduce part count. Modern designs typically migrate to i.MXRT or i.MX 8M, but the i.MXL remains supported in legacy medical, industrial, and aerospace programs. When designing with this device, allocate generous BGA escape routing and matched-length groups for the SDRAM bus. Use the BSDL or JTAG interface for boundary-scan test, and follow the NXP hardware design guide for power-rail sequencing to avoid latch-up at cold start.

MC9328MXLDVP15R2

MC9328MXLDVP15R2 - i.MXL ARM920T 200MHz MPU | NXP | MAP-BGA-225

The NXP (formerly Freescale) MC9328MXLDVP15R2 is the i.MXL applications processor built around the ARM920T core, offered in a 225-pin MAPBGA (13x13 mm, 0.80 mm pitch) package and supplied on tape-and-reel. It is a member of the DragonBall family and is specified for a 150 MHz operating frequency in the DVP15 speed grade (the parent family supports up to 200 MHz on other grades), 32-bit RISC architecture, and a 1.8 V core supply. Integrated on-die peripherals include a USB device controller, an LCD controller, and an MMC/SD host controller, together with the ARM920T MMU and standard system blocks (interrupt controller, timers, UARTs, SSI/SPI, I2C, PWM, A/D). The DVP variant suffix also denotes the dry-pack / tape-and-reel shipping option. What is an applications processor? An applications processor is a highly integrated system-on-chip (SoC) microprocessor that combines a CPU core (here ARM920T, an early ARM9 family core), memory-management hardware, graphics/display peripherals, and connectivity IP into a single device. Applications processors sit hierarchically below 'microprocessor' and above 'MCU' in the embedded taxonomy: they target richer operating systems (Linux, WinCE) than typical MCUs and provide higher clock rates plus richer peripheral integration than discrete microcontrollers. The i.MXL specifically evolved from Freescale's DragonBall line (68K ancestry) into the ARM9 era, positioning itself as a low-power multimedia-capable processor for handheld and portable products. Key features of the MC9328MXLDVP15R2 include: ARM920T core with MMU and separate 16 KB instruction / 16 KB data caches; integrated LCD controller capable of driving color STN/TFT panels; USB 1.1 device port; MMC/SD host bus interface for removable storage; SSI/SPI, UART, I2C, fast-infrared (FIR) and PWM peripherals; A/D converter and GPIO; 1.8 V core / 3.3 V I/O dual-rail supply; and a 225-pin MAPBGA package. The combination of on-die peripheral richness and low power consumption made the i.MXL a popular choice for PDAs, industrial handhelds, and early-generation smart devices in the early-to-mid 2000s. Technically, the ARM920T core implements the ARMv4T instruction set, supporting both 32-bit ARM and 16-bit Thumb instructions for code-density optimization. The 225-ball MAPBGA uses a 0.80 mm pitch on a 13x13 mm body, allowing compact PCB layouts suitable for handheld enclosures. The device also integrates a 16-entry write buffer and a 32-bit external system bus, with boot options from external NOR flash, NAND flash, or serial ROM depending on system configuration. Typical applications include PDA / handheld organizers, industrial data terminals, portable medical monitors, point-of-sale terminals, low-end smart appliances, and embedded Linux / WinCE demonstration platforms. In each of these, the i.MXL's integrated LCD controller, MMC/SD host, and USB device eliminate the need for companion controller chips, reducing BOM cost and PCB area. When designing with this part, note that the 1.8 V core rail typically requires an external LDO from a 3.3 V source; bulk decoupling on each supply pin and short trace routing to ground vias are essential for the high-frequency core. Because the MC9328MXLDVP15R2 is a long-EOL part now serviced only through authorized aftermarket distributors (e.g. Rochester Electronics), designers planning new designs should evaluate current NXP i.MX RT or i.MX 6/7/8 successors instead.

MC9328MXLVM15 - i.MXL ARM920T MPU 150MHz 256-MAPBGA | NXP

The NXP MC9328MXLVM15 is an i.MXL applications processor built around the ARM920T core, running up to 150 MHz, packaged in a 256-ball MAPBGA (14x14 mm) and offered as part of the Freescale/NXP DragonBall MX family. It integrates an LCD controller, USB device, and MMC/SD host controller into a single chip, alongside 32-bit addressing and a rich set of on-chip peripherals. An applications processor (AP) is a system-on-chip (SoC) class microprocessor that integrates a CPU core, memory controllers, and peripheral IP blocks so a portable product can be built with minimal external logic. The MC9328MXL belongs to the hierarchy ARM core -> ARM9 family -> ARM920T -> i.MX -> i.MXL applications processor -> embedded multimedia MPU, sitting at the apex of NXP's low-power multimedia line for handheld and portable designs. Key features of the MC9328MXLVM15 include an ARM920T core with 16 KB instruction cache and 16 KB data cache, a 128-bit external memory bus supporting SDRAM, NOR/NAND flash, and PCMCIA/CF cards, an integrated LCD controller capable of driving STN and TFT panels, a USB 1.1 device port, an MMC/SD host controller, and serial interfaces including UART, SPI, I2C, and I2S. Operating voltages are split between a 1.8V core supply and 3.0V I/O supply, with industrial-grade temperature options in the family. Architecturally, the ARM920T core implements the ARMv4T instruction set with a five-stage pipeline and separate instruction/data caches backed by a write buffer. The integrated LCD controller supports up to 800x600 resolution in passive color mode, and the system bus uses a multi-layer AHB fabric to keep peripheral DMA traffic from starving the CPU. Compared with the i.MX1 (MC9328MX1), the i.MXL family retains the same ARM920T core but typically ships at lower clock speeds and slightly different peripheral mixes. Typical applications for the MC9328MXLVM15 include portable media players, PDAs, smart handhelds, GPS navigators, industrial HMI panels, and early-generation e-readers. The on-chip LCD controller and SDRAM interface let engineers build a complete graphics terminal with only a power management IC, panel, and touch controller as external components. When designing with this part, ensure the 1.8V core and 3.0V I/O rails are brought up in the correct sequence to avoid latch-up, and place the boot-mode strapping resistors exactly as NXP specifies. Because the part is now end-of-life, consider long-term availability and second-source risk before committing new designs. This page consolidates distributor pricing, drop-in alternatives, application guidance, and engineering notes beyond the manufacturer datasheet to help engineers working with this legacy i.MXL part.

The i.MXL sits within the i.MX family hierarchy (i.MX1 → i.MX21 → i.MX25 → ...), which itself derives from the ARM9-based DragonBall/Freescale MX line; this positions the part at the low-power, mid-performance tier for handheld terminals, PDAs, and industrial HMI panels of its era. Key features include the ARM920T core with separate 16 KB instruction and 16 KB data caches, a Harvard MMU, integrated SRAM, an LCD controller with dedicated DMA, an external memory interface for SDRAM, NAND/NOR flash and PCMCIA/CF, plus USB 1.1 device, I²S audio, SPI, I²C, UART, and MMC/SD interfaces. Power management is handled via multiple on-chip voltage domains and clock-gating, supporting the low-duty-cycle workloads of battery-powered products. Architecturally, the ARM920T core pairs a Harvard cache structure with a write buffer and a full MMU, allowing Linux and WinCE operating systems to run natively. The integrated peripherals share an AHB/APB bus fabric, with DMA channels to offload the CPU during display refresh and memory-move operations. The 200 MHz speed grade enables QVGA/VGA-resolution LCD output without external graphics hardware. Typical applications include handheld data terminals, industrial HMI panels, portable medical instruments, point-of-sale terminals, MP3/multimedia players, and early-generation PDAs/smartphones. The wide peripheral mix makes the part a single-chip solution for products requiring display, touch input, removable storage (MMC/SD), and USB connectivity in a compact footprint. Designers should note that the MC9328MXLVM20 has been classified Obsolete/EOL by NXP. New designs should consider the modern i.MX RT or i.MX 6/7/8 families; this part remains in service only for legacy product maintenance, repair, and refurbishment. PCB designers must follow the 14 × 14 mm MAPBGA land pattern exactly, with controlled-impedance routing for SDRAM signals.

MC9328MXLVP15 - i.MXL ARM920T MPU 150MHz 225-MAPBGA | NXP

The NXP MC9328MXLVP15 is a member of the Freescale/NXP i.MX family of applications processors, integrating an ARM920T core running up to 150 MHz in a 225-ball MAPBGA (13x13 mm) package. It is a 32-bit RISC microprocessor with separate 16 KB instruction and 16 KB data caches, MMU support, and a rich set of integrated peripherals including an LCD controller, USB device, MMC/SD host, and synchronous serial interfaces. It targets power-efficient portable and embedded multimedia platforms. What is an applications processor? An applications processor is a system-on-chip category above a basic microcontroller: it integrates a high-performance CPU core (here ARM920T), memory controllers, dedicated hardware accelerators for multimedia (LCD, image sensors, audio), and standard connectivity peripherals. Applications processors sit between microcontrollers and full application processors in the IC hierarchy: microprocessor (MPU) -> applications processor -> SoC -> semiconductor. The i.MXL family is positioned for low-power handheld and industrial HMI products that need an LCD and modest multimedia without high cost. Key features include: 150 MHz ARM920T core with 16/16 KB I/D-cache and MMU; integrated LCD controller supporting STN and TFT panels; USB device (USB 1.1) controller; MMC/SD host controller; up to six integrated peripheral interface modules; wide operating voltage range with internal regulators; and a 225-contact MAPBGA (Mold Array Process Ball Grid Array) package sized at 13x13 mm with 0.80 mm ball pitch. The ARM920T core implements the ARMv4T instruction set, including the Thumb 16-bit compressed instruction subset for code-density-critical firmware. Integrated hardware blocks (LCD, USB, MMC/SD) offload the CPU, allowing it to focus on application logic. Power management is handled via run, doze, and stop modes and an on-chip PLL. Typical applications include portable media players, industrial HMI panels, GPS/PDA terminals, smart handhelds, point-of-sale terminals, and embedded control panels with graphical displays. The integrated LCD controller and low power consumption make the i.MXL especially well-suited for battery-powered graphical products. When designing with this part, verify the PCB layout accommodates the 0.80 mm ball pitch and provides adequate thermal relief - although power dissipation is modest, the MAPBGA requires proper via-in-pad or microvia fabrication. Existing i.MX firmware bootloaders and Linux BSPs are broadly reusable.

MC9328MXLVP15R2 - i.MXL ARM920T 32-Bit MPU, 150MHz | NXP | MAPBGA-225

The NXP MC9328MXLVP15R2 is a member of the DragonBall MXL (i.MXL) family of application processors built around the ARM920T core. It integrates a 32-bit RISC CPU running at up to 150 MHz, a 225-ball MAPBGA package on a 13 mm x 13 mm body with 0.80 mm pitch, and a single 1.8 V core supply rail. The part is offered on 13" tape-and-reel packaging (suffix R2) and targets human-interface and embedded control applications where the mature ARM920T ecosystem is valuable. A microprocessor (MPU/MCU) is an integrated circuit that contains a central processing unit, memory interfaces, and peripheral controllers on a single die. The i.MXL family belongs to the broader category of 32-bit embedded microprocessors -> system-on-chip (SoC) -> integrated circuits -> semiconductors. As a member of the ARM9E family tree (ARM920T core), the i.MXL executes the ARMv4T instruction set with both ARM and Thumb mode support, enabling efficient code density for resource-constrained designs. Key features include the ARM920T core with 16 KB instruction cache and 16 KB data cache, a Memory Management Unit (MMU) for protected operating systems such as Linux and WinCE, an integrated LCD controller capable of driving STN and TFT panels, a USB device controller, and an external memory controller supporting SDRAM, NOR flash, NAND flash, and PCMCIA/CF cards. Peripherals on the die include UARTs, an SPI interface, I2C, I2S audio, PWM timers, GPIO, real-time clock, and a 10-bit analog touch-screen controller. Architecturally the i.MXL combines a Harvard-cache ARM920T with an AMBA AHB/APB bus matrix and a wide external bus interface. The 150 MHz operation provides approximately 125 Dhrystone MIPS, while the 1.8 V internal supply (with separate I/O voltages, typically 1.8 V to 3.3 V) keeps dynamic power dissipation modest for the integration level. The MAPBGA-225 package offers strong thermal mass and an exposed-die paddle path for the cooling needs of handhelds. Typical applications include industrial human-machine interface (HMI) panels, point-of-sale (POS) terminals, portable data collectors, two-way radio / push-to-talk consoles, medical patient-monitoring handhelds, automotive telematics and infotainment controllers, and legacy PDA-class designs where the DragonBall software stack is preserved. The part is also widely used in OEM/ODM Linux/WinCE reference designs because of its mature driver tree. When designing with this part, place at least four 0.1 uF decoupling capacitors within 5 mm of the supply balls, provide the 32.768 kHz RTC crystal reference, and verify boot mode strap pins (BOOT[3:0]) before first bring-up. Designers should also evaluate migration to i.MX25 or i.MX28 for new designs because the i.MXL family is approaching end-of-life.

MC9328MXSCVF10

MC9328MXSCVF10 - i.MXS ARM920T MPU, 100MHz, 225-MAPBGA | NXP

The NXP (formerly Freescale) MC9328MXSCVF10 is an ARM920T-based 32-bit microprocessor from the i.MXS reduced-feature family of application processors, operating at up to 100 MHz and housed in a 225-ball MAPBGA (13x13 mm) package. It integrates the ARM920T core with the i.MX system-on-chip peripheral set, targeting cost-sensitive embedded designs that need full ARMv4 processing but with reduced peripheral content compared to higher-tier i.MX parts. The part is built on a 0.16 um CMOS process and is offered in a plastic MAPBGA-225 case outline (Case 1304B-01). An application processor is a microprocessor that integrates the CPU core, memory controller, and a configurable set of on-chip peripherals (timers, UARTs, I2C/SPI, USB, LCD controller, etc.) into a single die. Within the broader taxonomy it sits as: application processor -> microprocessor (MPU) -> integrated circuit -> semiconductor. The i.MXS sub-family is the streamlined derivative of the i.MX family, intended for handhelds, PDAs, industrial HMIs, and entry-level smart devices where BOM cost and PCB area matter more than peak graphics or multimedia throughput. Key features of the MC9328MXSCVF10 include a 32-bit ARM920T core with separate 16 KB instruction and 16 KB data caches, a system speed up to 100 MHz, integrated SDRAM/LCD/bus controllers, and the standard i.MX peripheral mix. The 225-MAPBGA package provides ample I/O for multimedia and connectivity while keeping the die in a manageable 13x13 mm footprint. Technically, the device pairs the ARM920T integer pipeline (which adds a hardware multiplier and supports the ARMv4 instruction set) with a system bus that ties the core to AHB peripherals. Designers should pair it with an external SDRAM and boot NOR/NAND flash; an MMU is included, so Linux and WinCE ports are feasible when memory footprint permits. Power management is handled by on-chip PLLs and a programmable frequency generator. Typical applications include PDAs, handheld terminals, industrial HMIs, point-of-sale terminals, simple web pads, and entry-level consumer electronics requiring a 32-bit ARM core. It is also a fit for low-cost industrial control panels and machine-to-machine gateways. Designers choose the MC9328MXSCVF10 specifically when the full i.MX feature set is unnecessary and BOM area must be minimized. When designing with this device, verify the BSP and Linux/WinCE support status against your chosen OS version, as the i.MXS family has been in long-term support mode. Ensure the PCB accommodates the 225-ball MAPBGA with proper microvia stack-up and matched-length SDRAM traces. Boot mode strapping and JTAG access must be planned at board level before layout is finalized.

MC9328MXSVP10

MC9328MXSVP10 - i.MXS ARM920T MPU 100MHz MAPBGA-225 | NXP

The NXP (formerly Freescale) MC9328MXSVP10 is an i.MXS applications processor built around an ARM920T core running up to 100 MHz, packaged in a 225-ball MAPBGA (13x13 mm, 0.8 mm pitch). It targets compact, low-power embedded products that need an integrated LCD controller and a USB device port on a single die. The 32-bit RISC core and on-chip peripherals make it suitable for portable HMI, point-of-sale, and home-automation designs. An applications processor is a highly integrated system-on-chip that combines a CPU core (here ARM920T, an ARM9-family implementation), memory interfaces, display and connectivity controllers, and power-management logic. Applications processors sit between microcontrollers (which emphasise on-chip flash and deterministic real-time control) and full application processors used in tablets and smartphones (which add high-speed multimedia and external DRAM). Within the broader taxonomy, this part is a microprocessor IC > microprocessor > MPU > applications processor > semiconductor. Key features include a 100 MHz ARM920T core with a 32-bit data bus, an integrated LCD controller for direct glass drive, a USB device controller, and power-saving modes for low standby consumption. The "V" in the part number indicates a commercial temperature grade, while the "P10" speed designator confirms the 100 MHz top frequency. Supply voltage spans 1.7V to 3.3V across the analog/digital and I/O rails. The part is the "Corsica" derivative of the i.MX family - a reduced-feature member designed specifically to support the .NET Micro Framework. Compared with the higher-tier i.MXL and i.MX1 members, the i.MXS drops the multimedia accelerator and some high-bandwidth peripherals but retains the LCD controller and USB device, which keeps power and BOM cost low for cost-sensitive HMI designs. The MAPBGA-225 package exposes the full bus and peripheral set while remaining reflow-compatible with standard lead-free assembly lines. Typical applications include remote controls, home-automation panels, point-of-sale terminals, HMI panels, and industrial controllers requiring a small footprint and an integrated display interface. The LCD controller reduces the need for an external graphics controller, while the USB device port enables direct PC or host connectivity for firmware updates and data exchange. When designing with the MC9328MXSVP10, pay attention to PCB stack-up and via-in-pad escape routing for the MAPBGA-225 footprint - the 0.8 mm pitch demands 4 or 6-layer boards with microvias. Provide separate analog and digital supply decoupling and respect the I/O voltage sequencing rules documented in the NXP datasheet to avoid latch-up.

It is a ROMless system-on-chip that integrates an ARM926EJ-S core with a memory management unit, LCD controller, USB 1.x host/device controller, and SDRAM controller on a single die manufactured in 0.13 um CMOS. An applications processor (AP) is a high-integration SoC designed to run an operating system and serve as the main CPU in embedded systems, going beyond a basic microcontroller by integrating multimedia interfaces, external memory control, and rich peripheral connectivity. The i.MX21 belongs to the i.MX family hierarchy: i.MX21 -> ARM9 applications processor -> applications processor -> microprocessor -> integrated circuit -> semiconductor. It enables product designers to add graphical user interfaces, touch input, and USB connectivity without a companion companion controller ASIC. Key features include an ARM926EJ-S core with 16 KB instruction cache and 16 KB data cache, an integrated LCD controller supporting TFT/STN panels, two USB 1.x controllers (host and device), an SDRAM controller, and an operating voltage range suitable for battery-powered handheld designs. The 289-LFBGA package with 0.8 mm ball pitch supports high-density board layouts while providing the signal integrity required for 350 MHz operation. The MC94MX21 uses a layered AHB/APB bus architecture with a JTAG debug interface, on-chip boot ROM options, and a comprehensive set of peripherals including I2C, SPI, UART, and SSI/I2S. Compared to the older i.MX1 (MC9328MX1), the i.MX21 boosts clock speed, memory addressing, and adds integrated LCD and USB On-The-Go support. Typical applications include industrial HMI panels, point-of-sale terminals, portable medical devices, portable data collectors, and consumer electronics requiring multimedia and connectivity features. The low-power design with operating temperature range of -40 C to +85 C supports industrial and outdoor deployments. Designers should provide proper power decoupling with 100 nF ceramic capacitors near each VDD ball and follow the NXP layout guide for the 289-LFBGA 0.8 mm pitch footprint to ensure manufacturing yield. USB signal traces must be 90 ohm differential and routed as short as possible to preserve signal integrity at USB 1.x full-speed operation.

MC9RS08KA1CDB - 8-bit RS08 MCU, 1KB Flash, 6-DFN | NXP

The NXP MC9RS08KA1CDB is an 8-bit RS08-core microcontroller with 1KB of flash memory, 128 bytes of RAM, an integrated analog comparator, and 6 general-purpose I/O pins, housed in a 6-DFN exposed-pad (3x3 mm) package and operating at up to 10 MHz. An entry-level 8-bit microcontroller (MCU) is the smallest class of programmable system-on-chip: it combines a processor core, program flash, data RAM, clock generation, reset supervision, and a few peripherals on one die. Within the hierarchy of embedded processors - MCU -> microcontroller unit -> embedded IC -> semiconductor - ultra-low-end MCUs like the RS08KA family target applications where a discrete logic solution would otherwise be used, replacing glue logic and analog timers with reprogrammable silicon at a comparable cost. Key features include the simplified S08-derived RS08 instruction set with high-performance LDA, STA, and CLR instructions, 1KB of on-chip flash (self-programmable), an analog comparator (ACMP), low-voltage inhibit (LVI) and power-on reset (POR) supervision, and multiple low-power modes. Supply operation spans 2.5V, 3.3V, and 5V rails, which simplifies integration into both legacy 5V systems and modern 3.3V designs. Architecturally, the RS08 core is a cost-reduced derivative of the industry-proven S08 (HC08 lineage) core from Freescale Semiconductor, now part of NXP Semiconductors. CISC-style addressing keeps code density high, important when program space is only 1KB. System protection features - COP watchdog, LVI, and POR - reduce external component count in cost-sensitive appliances and small consumer products. Typical applications include small appliance control, LED lighting and dimming, battery charger supervision, timer and sequencer replacement, and simple human-interface functions in cost-driven consumer electronics. The 3x3 mm 6-DFN footprint suits extremely space-constrained boards. Design consideration: this part is End-of-Life per the NXP product page, so new designs should verify remaining supply or plan a migration path; the 6-DFN footprint is shared with the pin-compatible MC9RS08KA2CDB, which doubles flash to 2KB.

The NXP MC9RS08KA1CPC is an 8-bit RS08 microcontroller with 1KB of Flash program memory, 63 bytes of RAM, and an integrated analog comparator, housed in an 8-pin PDIP (DIP-8) through-hole package. It runs at 10MHz internal bus frequency from a 1.8V to 5.5V supply and provides 4 general-purpose I/O pins plus dedicated reset and ACMP pins. An RS08 microcontroller is a reduced-instruction 8-bit core derived from the Freescale/NXP S08 family, optimized for ultra-low-cost, ultra-low-power embedded applications. It is part of the broader 8-bit MCU hierarchy (8-bit microcontroller -> microcontroller unit -> embedded controller -> semiconductor) and shares the HCS08 instruction set with the LDA, STA, and CLR extensions. Compared with the older HC08, RS08 cuts die area and cost while preserving the S08 peripheral ecosystem, making it suited for appliances, toys, lighting controllers, and battery-powered sensor nodes. Key features include 1KB Flash, 63-byte RAM, an internal clock source with trim, brown-out and low-voltage detect (LVD/POR), a watchdog timer, an on-chip analog comparator, and multiple STOP/WAIT low-power states. The internal oscillator eliminates the need for an external crystal in most designs, reducing BOM cost and PCB area in cost-sensitive products. Typical applications include low-end consumer white goods, remote-control transmitters, LED drivers, battery chargers, and simple sensor readouts. The DIP-8 package and wide operating range make it especially attractive for hobbyist, educational, and legacy-replacement designs where through-hole mounting is preferred for hand-prototyping or repair work. When designing with this device, ensure the supply stays within 1.8V-5.5V and that the I/O pins do not exceed their source/sink ratings. The internal analog comparator allows reaction to external analog signals without an external op-amp, simplifying BOM in cost-sensitive products.

The NXP Semiconductors MC9RS08KA1CSC is an 8-bit RS08KA microcontroller with 1 KB of flash memory, 63 bytes of RAM, an internal oscillator, and an 8-pin SOIC package. It targets cost-sensitive embedded applications requiring minimal code space and a compact footprint. The verified product information identifies a 10 MHz device in distributor listings, while another listing describes a 20 MHz RS08KA family; use the manufacturer datasheet for the exact operating-frequency and electrical limits before final design release. The RS08 core is a compact CISC processor built around the S08 instruction set with additional high-performance LDA, STA, and CLR instructions. This MCU is intended for simple control, sensing, and actuator tasks where a larger 8-bit MCU would add unnecessary cost, memory, and board area. Its 63-byte RAM and 1 KB flash are sufficient for startup code, basic state machines, and tightly bounded control logic rather than general-purpose applications. The device operates from a low-voltage supply suitable for embedded and battery-oriented designs, with an internal oscillator eliminating a mandatory external clock source. The RS08KA family also includes timer and interrupt resources for periodic sensing and event handling. Power-management features and the small package help reduce both board footprint and system complexity in cost-driven products. Typical uses include simple keypad or button interfaces, low-speed motor and relay controllers, basic sensor nodes, household appliance controls, and auxiliary embedded functions. The compact SOIC-8 outline is useful when through-hole or leaded assembly is preferred, but its 1 KB program memory is a strict constraint for larger control algorithms. When designing around MC9RS08KA1CSC, verify the exact pin multiplexing, reset behavior, oscillator limits, and supply-voltage range in the NXP datasheet. Avoid assuming that all RS08 family members are software-compatible, because memory size and peripheral configurations can differ. A migration to a larger MCU may be required if the application grows beyond the 63-byte RAM and 1 KB flash budget. This product page combines verified distributor data, lifecycle information, package details, design constraints, and an honest assessment of alternative availability. It is intended to help engineers quickly determine whether this RS08KA device fits a minimal embedded-control design before requesting documentation and sourcing support.

The RS08 belongs to the 8-bit MCU product class within the broader microcontroller hierarchy (8-bit MCU -> microcontroller -> embedded computing -> semiconductor). It is intended for cost-sensitive, space-constrained designs that still need deterministic, low-power embedded control. Key specifications: the MC9RS08KA2CDB operates from a 1.8 V to 5.5 V supply (typical operating points 2.5 V/3.3 V/5 V), includes 2KB (2K x 8) of Flash, 63 x 8 RAM, and 4 GPIO. The internal analog comparator (ACMP) listed on some distributor variants is the key analog peripheral in this family, enabling simple threshold detection without an external op-amp. In design, the RS08 core uses a simplified S08 instruction set plus high-performance LDA, STA, and CLR instructions, allowing efficient C and assembly code generation on a tiny Flash budget. The 6-pin DFN-EP footprint with exposed pad gives a low thermal-resistance path and minimal PCB area, suited to coin-cell or battery-powered sensor nodes and appliance user-interface replacement. Typical applications: low-end consumer appliances, replacement of discrete logic + analog timer ICs, AC/DC wall-cube controller interfaces, simple LED drivers, battery chargers, and remote controls. The combination of small package, integrated LVD/POR, and ACMP lets one chip replace multiple discrete components. Design consideration: because only 4 I/O pins are available, designers must budget pin functions carefully — for example, one pin may be shared between ADC input, ACMP input, and external interrupt. Always connect the EP (exposed pad / pin 6 in some outlines) to the ground plane for thermal and electrical performance.

MC9RS08KA2CPC - 8-bit RS08 MCU, 2KB Flash, DIP-8 | NXP

The NXP MC9RS08KA2CPC is a 8-bit RS08 microcontroller with 2KB flash memory, 62 bytes of RAM, and an integrated analog comparator, housed in an 8-pin PDIP package. The device operates at up to 10 MHz bus frequency and is designed for ultra-low-end embedded control applications where minimal memory and low cost are priorities. An 8-bit microcontroller (MCU) is a small computer-on-a-chip containing a CPU core, flash program memory, RAM, and peripheral set on a single silicon die. Within the semiconductor taxonomy, the MC9RS08KA2CPC sits in the hierarchy: 8-bit MCU -> RS08 family microcontroller -> Freescale/NXP Kinetis-era low-end MCU -> embedded microcontroller -> integrated circuit. The simplified S08 instruction set adds LDA, STA, and CLR high-performance instructions to support compact code density. Key features include 2KB flash program memory, 62 bytes RAM, an integrated analog comparator for sensor interfacing, a low-voltage inhibit (LVI) module, power-on reset (POR), and an internal clock source. The 8-pin PDIP package supports through-hole PCB mounting, which simplifies prototyping, breadboarding, and low-volume production without surface-mount reflow equipment. The device also supports background debug mode (BDM) for in-circuit programming and debugging. The MC9RS08KA2CPC uses the RS08 central processor unit, which is a streamlined variant of the S08 core optimized for low pin-count applications. With the simplified instruction set, deterministic interrupt handling, and low quiescent current, the part targets cost-sensitive applications that require just enough compute to read sensors, drive outputs, and manage simple state machines. The internal oscillator and integrated analog comparator reduce external component count. Typical applications include consumer appliance controls, lighting controllers, simple sensor interfaces, battery chargers, and white goods. The combination of analog comparator, internal clock, and low pin count suits designs where the MCU is paired with a single analog signal and a few digital outputs. When designing with this part, note that the DIP-8 package requires through-hole PCB pads and clearance holes, which is unsuitable for high-density SMT boards. For new designs in this performance class, evaluate NXP's S08PT or S08P families, or Microchip's PIC16F or ATtiny families, which offer modern peripherals and active lifecycles. This page consolidates the verified NXP product information, datasheet links from distributor sources, and pin-compatible drop-in alternatives into a single engineer-ready reference not found in the standalone manufacturer datasheet.

MC9RS08KA2CPC174 - 8-bit RS08 MCU 2KB Flash 20MHz | NXP

The NXP (Freescale Semiconductor) MC9RS08KA2CPC174 is an 8-bit RS08-core microcontroller with 2KB (2K x 8) FLASH memory, a 20MHz maximum CPU clock, and an 8-pin PDIP package. The RS08KA family is specifically crafted for the ultra-low-end market, delivering minimal memory, low power consumption, and cost-effective basic embedded control in an exceptionally small footprint. An 8-bit microcontroller (MCU) is a single-chip computer whose data bus is 8 bits wide, integrating a processor core, program memory (FLASH), RAM, I/O ports, and system protection into one package. Within the MCU hierarchy, the RS08 family sits below the S08 and HC08 families as a simplified, cost-optimized core retaining S08-derived instruction efficiency. Key features of the MC9RS08KA2 include the RS08 central processor unit with a simplified S08 instruction set augmented by high-performance LDA, STA, and CLR instructions, 2KB on-chip FLASH program memory, and 20MHz internal bus operation. System protection features and ultra-low-end cost positioning make it a direct drop for discrete logic and simple state-machine designs. Technically, the RS08 core streamlines the classic HC08/S08 architecture, reducing gate count and die size while preserving code compatibility concepts familiar to HC08 developers. The internal oscillator removes the need for external crystals in many designs, lowering bill-of-materials cost and board area. Typical applications include small appliance control, simple sensor interfacing, LED and indicator sequencing, low-cost battery chargers, and replacement of glue logic in industrial boards. The through-hole 8-PDIP package suits prototypes, legacy repair, and hand-soldered production. Design consideration: verify the availability status of this Rochester Electronics-distributed suffix, as the original Freescale device is a legacy part; plan second sourcing accordingly. This page synthesizes distributor pricing context, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, providing engineering value beyond a standard product listing.
