MC9S08JM60CQH

MC9S08JM60CQH - 8-bit S08JM MCU, 60KB Flash, USB, 64-QFP | NXP

The NXP MC9S08JM60CQH is an 8-bit S08JM-family microcontroller built on the HCS08 CPU core, delivering 48 MHz core clock with 24 MHz internal bus frequency and 60 KB of on-chip FLASH program memory, packaged in a 64-pin QFP (14x14 mm). It integrates a USB 2.0 full-speed device controller, dual analog comparators, multiple low-power modes, and a background debug module, targeting cost-sensitive consumer and industrial designs that need standard USB connectivity. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, FLASH program memory, peripherals, and I/O on one die. Within the semiconductor taxonomy, MCUs fall under integrated circuits > microcontrollers, and the S08JM sits in NXP's entry-level 8-bit USB portfolio — positioned between simple 5V 8-bit MCUs and higher-end 32-bit ARM Cortex-M0 parts. Its role in a system hierarchy is to handle local sensing, user I/O, housekeeping, and wired USB connectivity while keeping bill-of-materials cost and firmware complexity low. Key features include 60 KB FLASH with in-application programming support, 4 KB SRAM, 51 general-purpose I/O pins, an on-chip USB 2.0 full-speed device transceiver (no external PHY required), two analog comparators with selectable trigger inputs, a 16-bit modulo timer, an 8-channel 12-bit ADC, and low-power STOP and WAIT modes drawing microamp-level standby current. The HC08 instruction set plus the BGND instruction simplifies background debugging, while the on-chip ICE module with two comparators and nine trigger modes supports in-circuit emulation with an 8-deep FIFO for change-of-flow tracing. Architecturally, the JM60 uses a von-Neumann HCS08 core with a 24 MHz internal bus feeding the FLASH, peripherals, and USB engine. The integrated USB transceiver, dual 5V-tolerant analog comparators, and wide 2.7 V to 5.5 V supply range reduce external component count. The 64-QFP (14x14 mm) package has 51 GPIO plus supply, ground, and reference pins, suiting through-hole-friendly industrial layouts while still allowing hand-rework. Typical applications include USB HID peripherals (keyboards, mice, game controllers), USB-to-UART bridges, point-of-sale terminals, low-cost data loggers, and industrial control panels with USB diagnostic ports. For designs needing only serial connectivity without USB, designers often migrate to the S08AC family; for higher compute and more memory, NXP's S12 and Kinetis lines are typical step-ups. When designing with this part, provide a clean 3.3 V regulated rail from the USB VBUS line, use the recommended 12 MHz or 16 MHz external crystal for USB-accurate clocking, and place 100 nF decoupling caps within 5 mm of every supply pin. The integrated USB transceiver still requires precise PCB layout and a 90-ohm differential DP/DN trace to pass compliance.

Existing products may still be supported through distributor inventory or legacy procurement, but the product status should be checked against current authorized-channel availability. The USB peripheral, memory size, clock rate, and package dimensions must also be confirmed against the original schematic and pin assignment. A key design consideration is the difference between nominal distributor inventory and guaranteed production supply. Engineers should review the NXP product-change and lifecycle information, validate USB electrical requirements, preserve programming and debug access, and confirm that replacement parts are truly pin-to-pin compatible rather than merely similar in function. For obsolete-device migrations, a redesign may be necessary if firmware, USB descriptors, or peripheral assignments depend on target-specific behavior. This page consolidates verified distributor specifications, lifecycle information, application context, and sourcing guidance for engineers evaluating the MC9S08JM8CLC. It is intended to support initial design review and procurement decisions, while acknowledging that unreported electrical limits, pin names, memory-map details, and pricing should be confirmed from the current manufacturer datasheet.

Its integrated USB controller makes it useful as the principal application processor in compact USB peripherals, where a higher-performance MCU would add cost or design complexity without providing a corresponding system benefit. Typical uses include USB-connected data acquisition devices, portable instrumentation, configuration tools, simple human-interface peripherals, and industrial service interfaces. Designers can place the device between a USB connector and the controlled subsystem, then use its on-chip USB peripheral to exchange serial data while timers, communications peripherals, and general-purpose I/O handle local control functions. When laying out the board, route USB D+ and D- as a controlled impedance differential pair and minimize the distance between the controller, connector, and protection components. Confirm the pin-multiplexing and alternate-function requirements in the manufacturer pin-description table, and account for every supply and ground connection before routing. Because the device is listed as end of life, new production designs should include a formal lifecycle and sourcing review. This page combines the manufacturer's lifecycle information, distributor specifications, technical search results, and application-oriented engineering guidance to clarify where the MC9S08JM8CLD fits. It also distinguishes verified drop-in options from merely similar devices, helping engineers avoid assuming that equal flash capacity and package size guarantee peripheral, pinout, timing, or software compatibility.

It is housed in a 20-pin SOIC (SOIC W) wide-body package suitable for industrial temperature ranges of -40C to +85C, with single-supply operation from 2.7 V to 5.5 V. What is an S08 8-bit microcontroller? The S08 is NXP's (formerly Freescale) 8-bit CISC microcontroller family built around the HCS08 CPU core, which succeeds the legacy HC08 family with an enhanced instruction set, hardware multiply/divide in the accumulator, and a richer peripheral integration strategy. An 8-bit MCU like the MC9S08JS16CWJ is typically chosen when the application requires simple deterministic firmware, USB connectivity, low cost, and easy development with CodeWarrior or the newer Eclipse-based S08 toolchains, rather than the raw processing throughput of a 32-bit Cortex-M device. Key features that differentiate this part include the integrated USB 2.0 full-speed (12 Mbps) device controller with an on-chip transceiver that eliminates external USB PHY components, 16 KB of flash with 512 bytes of RAM, multiple serial interfaces (SCI, SPI), and a hardware LIN bus capability for automotive sub-bus applications. The part operates from a single 3.0 V or 5.0 V supply rail and supports background debugging via the standard BDM interface. The on-chip regulator and low-power run/wait/stop modes suit battery-powered USB peripherals such as HID input devices and low-data-rate industrial sensors. The MC9S08JS16CWJ combines a 48 MHz CPU, 24 MHz bus, hardware multiply, and integrated USB into a compact 20-pin SOIC footprint, simplifying BOM and PCB area versus an external MCU + ULPI/UTMI PHY architecture. The on-chip pull-up on the D+ line and integrated 3.3 V USB regulator are particularly valuable for cost-sensitive USB peripheral designs. Typical applications include USB HID input devices (keyboards, mice, custom HID peripherals), USB-to-UART bridge dongles, low-cost industrial sensor interfaces that expose a USB CDC or vendor-class endpoint, and LIN-to-USB or RS-232-to-USB protocol-converter dongles. The wide operating voltage and integrated transceiver make it a strong fit for any USB peripheral that must interface with a PC host. When designing with this part, ensure that the USB D+ pull-up (1.5 kohm to 3.3 V) is enabled in firmware after bus attach is desired, and add ESD protection (such as a USBLC6-2SC6 array) on D+/D- lines for production robustness. Decouple VDD and the USB voltage-domain pins with 100 nF and 4.7 uF ceramic capacitors placed within a few millimetres of the IC pins, and follow standard USB 2.0 differential-pair impedance (90 ohm differential) for the D+/D- traces.

The defining feature of the JS16 family is its full-speed USB 2.0 device controller with an on-chip USB transceiver, eliminating external transceiver components and reducing bill-of-materials cost. Supporting peripherals include LVD (low-voltage detect), POR (power-on reset), and PWM modules, with connectivity via LINbus, SCI, and SPI in addition to USB. An internal oscillator option removes the need for an external crystal in many designs. The HCS08 CPU executes at up to 48MHz with a 24MHz internal bus, delivering efficient interrupt-driven operation for USB endpoint servicing. The 16KB Flash accommodates USB stack firmware alongside application code, while 512 bytes of RAM handle endpoint buffers and application variables. The 24-VQFN exposed-pad package provides compact 5x5 mm footprint suitable for space-limited PC peripheral boards. Typical applications include affordable PC peripherals such as HID devices, USB dongles, sensor bridges, and game controllers - applications the NXP product page explicitly targets. The integrated USB transceiver makes it a strong fit for compact, low-cost USB-to-UART or USB-to-SPI bridges. Designers should budget RAM carefully: with only 512 bytes, USB endpoint buffering and application data must be allocated conservatively. Enabling the internal oscillator saves a crystal but verify USB timing tolerance in your design.

An 8-bit MCU (microcontroller unit) is a single-chip computer that integrates a CPU, memory, and peripherals on one die. The HCS08 core is a von-Neumann 8-bit CPU executed from a common Flash/ROM address space, designed for predictable interrupt latency and ultra-low standby power. Microcontrollers sit at the foundation of every embedded system; 8-bit variants are favored when cost, deterministic behavior, and peripheral integration (LCD, USB, CAN) outweigh raw compute throughput. Key features of the MC9S08LC60LH include 60 KB on-chip Flash, 4 KB RAM, an internal LCD driver with up to 8 backplanes and configurable segment count, a USB 2.0 full-speed device controller, a CAN 2.0 A/B module, two SCI, one SPI, and up to 18 GPIO pins. The CPU runs up to 40 MHz (20 MHz bus) from a 1.8 V to 3.6 V supply, supporting both lithium-cell and 3.3 V regulated rails. Architecturally, the S08LC uses the HCS08 instruction set (object-code compatible with HC08 plus BGND for debugging), a 3-stage pipeline, and a multi-tier clock gating scheme that allows peripherals to be gated individually during STOP modes. The integrated LCD charge pump supports both glass types and contrast over temperature. Typical applications include metering and instrumentation, medical devices, white-goods HMIs, industrial control panels, and consumer products requiring segment-LCD displays with USB connectivity. The CAN interface makes it attractive in automotive body and appliance networks. When designing with this part, allocate PCB area for the LCD segment pins (which form a large portion of the LQFP-64 ballout) and place the external 32.768 kHz crystal close to the XTAL pins to minimize stray capacitance.

Designers should account for the exposed-pad thermal path, maintain the required input and decoupling connections, and verify display and peripheral assignments against the manufacturer pin-description table. Because the product is designated End of Life by NXP, long-life programs should confirm availability, lifecycle transition timing, and approved sourcing arrangements before committing new production designs. This page organizes the manufacturer specifications, lifecycle status, packaging information, practical application guidance, and engineering considerations needed to evaluate the MC9S08LL8CGT for a new or legacy embedded-control design.

MC9S08LL8CLF - 8-Bit 20MHz 10KB Flash MCU | NXP

The NXP Semiconductors MC9S08LL8CLF is an ultra-low-power 8-bit S08 microcontroller with 10KB Flash, 2KB RAM, a 20MHz core, integrated LCD drive and touch-sensing capability in a 48-LQFP 7x7 mm package. It is designed for battery-powered portable products, including medical diagnostics and handheld appliances. An 8-bit microcontroller is a programmable embedded-control component combining a CPU core, memory, timers, serial interfaces and application-specific peripherals on one integrated circuit. The S08 architecture belongs to the microcontroller hierarchy, where firmware acquires inputs, executes control logic and manages displays, sensors and communication. Its 8KB Flash stores the operating program, while its 2KB RAM supports working data and stack operations. The verified feature set emphasizes 20MHz processing, 10KB Flash and an LCD driver. Additional NXP product information identifies integrated touch sensing for portable designs. This combination can reduce the number of external display-interface or touch-input components, although the complete peripheral set, current limits and timing parameters must be confirmed in the manufacturer datasheet before schematic release. The MC9S08LL8CLF is an S08LL-family device aimed at low-energy embedded products. Its integrated LCD and touch functions make it especially relevant to compact human-interface equipment where display dimensions, battery life and board area are tightly constrained. The 48-LQFP package exposes more interface pins than a minimal microcontroller package, supporting integration while requiring a correspondingly dense PCB footprint. Typical uses include handheld diagnostic instruments, low-power measurement products and small appliances with LCD feedback. Designers should program the LCD segments correctly, budget code and RAM usage early, and validate startup behavior from the device datasheet. Because the product page reports End of Life, new production should be qualified before committing to a long-life design. For an end-of-life migration, do not assume that another S08 part is drop-in compatible. Confirm the 48-LQFP footprint, pin assignments, LCD segment mapping, touch channels, memory organization, supply voltage, clock setup and firmware dependencies. The verified alternatives data does not identify five confirmed pin-to-pin replacements, so candidate parts must not be promoted as drop-ins without manufacturer evidence. This page consolidates current distributor references, lifecycle information and design guidance for the MC9S08LL8CLF. It also highlights sourcing risk and the distinction between electrical similarity and a genuine pin-to-pin replacement, information that is essential when maintaining an aging embedded design.
