MC9S08GW64CLK - 8-bit S08 MCU, 64KB Flash, 20MHz, 80-LQFP | NXP

The NXP MC9S08GW64CLK is an 8-bit microcontroller from the S08GW family built on the proven HCS08 CISC core, integrating 64KB of on-chip Flash and operating at up to 20MHz bus frequency, housed in an 80-pin LQFP package (14x14 mm). The device is purpose-designed for single-phase electricity meters, gas flow meters and water flow meters, integrating two independent 16-bit SAR analog-to-digital converters and a programmable pulse counter with built-in sensor-decoding logic for automatic metering. An MCU (microcontroller unit) is a single-chip computer containing a CPU core, non-volatile program memory (Flash/ROM), volatile working memory (RAM), and a mix of analog and digital peripherals. The 8-bit class targets cost-sensitive, deterministic, low-power applications where an arithmetic logic unit operating on byte-wide data is sufficient. The S08 family is NXP/Freescale's evolution of the legacy HC08 architecture, adding single-wire background debug (BDC), improved Flash endurance, and lower active/idle current. Key features of the MC9S08GW64CLK include 64KB Flash, 4KB SRAM, two 16-bit SAR ADCs with programmable delay trigger, a TSI (Touch Sensing Input) interface, RTC, multi-channel timer/PWM, and a wide 2.1V-3.6V supply range with on-chip voltage regulator. The integrated LCD driver (in the GW family) supports metered-segment displays without an external driver IC. Security is provided by a unique 80-bit device ID and Flash security/lock bits for anti-tamper metering. The S08 core uses a von Neumann architecture with 16-bit stack pointer and index registers, executing a CISC instruction set fully upward-compatible with the HC08. Two independent ADCs sample voltage and current channels simultaneously, enabling accurate real-power calculation in single-phase electricity meters without external sample-and-hold synchronization hardware. Typical applications include single-phase electricity meters, gas and water flow meters with pulse or encoder outputs, smart metering data concentrators, industrial sensor transmitters, and low-power battery-driven measurement nodes. The wide operating temperature range and integrated metrology peripherals reduce BOM cost versus discrete ADC + external MPU designs. When designing with the MC9S08GW64CLK, place the 32.768 kHz XTAL and load capacitors as close to the XTAL pins as possible, and route the analog inputs (ADP1/ADP2) with short guarded traces to minimize metrology error. The device is currently flagged End-of-Life by NXP, so long-life industrial metering programs should validate the last-time-buy window and plan a migration to the S08PL or S08MM family. This page synthesizes distributor inventory, parametric data, and cross-reference guidance not always available on the manufacturer product page, including drop-in alternatives verified to share the 80-LQFP footprint and key peripheral set.

It integrates I²C, SCI, SPI, USB, PWM, watchdog, low-voltage detection, and power-on reset peripherals for compact control designs. The verified listing identifies the device as obsolete, so procurement should prioritize inventory review rather than new long-term design commitments. A microcontroller is a semiconductor that integrates a CPU, memory, and peripherals into one device for embedded control. The S08 MCU family belongs to the broader hierarchy of 8-bit microcontroller, embedded processor, and integrated circuit. Such devices sit between simple logic controllers and higher-performance microprocessors, providing enough deterministic I/O and serial connectivity for motor, appliance, communications, and industrial-control tasks without requiring an external processor.

USB, PWM, low-voltage detection, power-on reset, and watchdog functions reduce the need for separate support devices in suitable embedded systems. The 81-map BGA package requires careful PCB design because its fine-pitch balls are not visually accessible after assembly. Its 10 mm by 10 mm land pattern demands accurate escape routing and manufacturing controls. Although the package is compact, real implementation depends on the complete ball map, exposed thermal or power balls, and recommended PCB stack-up specified by the manufacturer datasheet. The provided search data does not include individual ball names or the complete pinout, so those details are not inferred here. Typical uses include USB-connected control peripherals, small industrial controllers, sensor hubs, keypad interfaces, actuator controllers, and compact consumer products. At 48 MHz, the S08 core can service interrupt-driven serial links and real-time I/O, but firmware architecture must account for interrupt latency and peripheral timing. The 128 KB Flash capacity is suitable for substantially more code than a very small state-machine controller, while 12 KB of RAM supports communication buffers and intermediate state. For new designs, engineers should first confirm lifecycle availability, then verify the exact suffix, package drawing, ball map, clock configuration, memory map, and USB electrical requirements. Existing products may still be supportable through last-time-buy or inventory channels, but no unverified transition status, operating-temperature grade, voltage range, or package thermal data is assumed. This page distinguishes verified distributor facts from parameters that require direct datasheet confirmation. This page consolidates verified distributor listings, the obsolete-status signal, memory and connectivity details, sourcing guidance, and engineering cautions. It is intended to accelerate identification and lifecycle review while avoiding unsupported substitutions for an obsolete 81-map BGA microcontroller.

MC9S08JM32CQH - 48MHz 32KB Flash USB MCU | NXP | 64-QFP

The NXP Semiconductors MC9S08JM32CQH is an 8-bit S08JM microcontroller with a 48 MHz HCS08 CPU, 32 KB of Flash memory, and USB 2.0 full-speed device connectivity in a 64-QFP 14 x 14 mm package. The verified product listing also identifies CAN connectivity, making this device suited to compact embedded controllers that exchange serial data while coordinating peripheral or automotive functions. Its combination of 32K x 8 Flash, 48 MHz processing, USB, and CAN positions it between simple 8-bit I/O devices and more complex communications controllers. An 8-bit microcontroller is a programmable integrated circuit that executes firmware from embedded nonvolatile memory and reads sensors or operates actuators through digital and analog peripherals. MC9S08JM32CQH belongs to the S08 family of HCS08-based microcontrollers. USB enables connection to a host computer or other USB controller, while CAN supports robust communication between embedded nodes. Together, these interfaces can standardize data exchange in industrial, consumer, and automotive-oriented control systems without requiring a separate protocol transceiver on the digital side of the design. The verified data identifies an S08 core, 48 MHz CPU frequency, 32 KB Flash organized as 32K x 8, and a 64-QFP package measuring 14 x 14 mm. It also identifies on-chip USB 2.0 full-speed device support and CAN connectivity. Other details such as SRAM capacity, analog peripherals, operating voltage, temperature limits, timers, and electrical timing were not supplied in the verified extract and therefore must be confirmed in the NXP datasheet before design release. At 48 MHz, the CPU provides substantially more instruction throughput than many basic 8-bit controllers while retaining the relatively simple programming and peripheral model associated with the S08 architecture. USB and CAN integration can reduce external component count in a connected embedded product. The trade-off is that firmware must account for USB enumeration, CAN timing, and protocol state while remaining within the device's documented memory and peripheral limits. Typical uses include USB-connected industrial controls, automotive accessory controllers, CAN-connected nodes, USB-to-CAN interface equipment, human-interface panels, and compact embedded data-acquisition modules. The device is most appropriate when an existing S08-based design needs both USB device connectivity and CAN support rather than a high-end processor or a separate communications bridge. Before schematic capture, verify the 64-pin assignment, power rails, decoupling requirements, oscillator options, reset configuration, USB transceiver support, CAN physical-layer requirements, programming interface, and package tolerances directly against the NXP datasheet. PCB layout should reserve USB differential routing and controlled impedance support, while CAN requires an external physical-layer transceiver unless the selected board architecture provides one elsewhere. This product synthesis separates verified identity and headline specifications from unverified electrical details. It combines distributor availability references, lifecycle information, interface suitability, and practical design cautions so procurement and engineering teams can evaluate the MC9S08JM32CQH without treating missing datasheet parameters as established facts.

MC9S08JS8LCFK - 8KB Flash USB MCU 48MHz | NXP S08JS

The NXP MC9S08JS8LCFK is an 8-bit S08JS microcontroller with an integrated USB 2.0 full-speed device controller, 8KB of Flash program memory, and an on-chip USB transceiver, housed in a 24-pin HVQFN (5x5 mm) package with an exposed thermal pad. It operates at up to 48 MHz internal bus frequency and supports both 3.3V and 5V supply rails, making it a one-chip solution for USB peripherals that previously required an external USB transceiver and a separate MCU. An 8-bit microcontroller (MCU) is a small computing system-on-chip that integrates a CPU, memory (Flash/RAM), and configurable peripherals onto a single silicon die. The HCS08 CISC architecture used in the S08 core family is a low-power, deterministic instruction set that simplifies firmware development for cost-sensitive embedded products. Within the broader taxonomy, the MC9S08JS8LCFK sits as: 8-bit MCU -> microcontroller -> integrated circuit -> semiconductor. By integrating a USB 2.0 transceiver and PHY directly on die, NXP helps engineers reduce BOM cost and PCB area versus two-chip USB designs. Key features of the MC9S08JS8LCFK include: 8 KB Flash program memory for USB class firmware, integrated USB 2.0 full-speed (12 Mbps) device controller with on-chip transceiver, 24-pin HVQFN 5x5 mm package with thermal pad, industrial temperature grade support, and on-chip debug (BKGD) plus enhanced clock generation. The integrated USB PHY eliminates external pull-up resistors and the off-chip transceiver IC typically required by legacy USB designs. The HCS08 core executes most instructions in 1-2 bus cycles, and an internal 48 MHz clock drives the USB module to maintain precise 12 Mbps full-speed signaling. The 8KB Flash is in-system programmable via the background debug mode (BDM), supporting field updates. Multiple low-power modes (Stop, Wait, Run) plus an internal low-power oscillator optimize battery-powered USB peripherals. Typical applications include USB Human Interface Devices (HID) such as keyboards, mice, and game controllers, USB-to-UART bridge dongles, USB class-compliant barcode scanners, industrial USB sensors, low-cost USB peripherals and consumer accessories where a 48 MHz 8-bit core is sufficient and BOM cost dominates. When designing with this part, ensure the D+ pull-up resistor (1.5 kohm to 3.3V) is correctly placed, the VBUS pin is properly decoupled, and the exposed thermal pad is soldered to the ground plane for thermal and electrical performance. The 24-pin HVQFN requires careful PCB layout - the e-pad must have multiple thermal vias to dissipate heat. This page synthesizes drop-in alternatives, comparison tables, design notes, and pricing not aggregated elsewhere; engineers can quickly determine whether the MC9S08JS8LCFK fits their USB peripheral design versus the larger JS16, SH8, or QG8 family siblings.

MC9S08LC36LH - 8-bit S08LC MCU, 36KB Flash, 40MHz, LCD | NXP

The NXP MC9S08LC36LH is an 8-bit HCS08-family microcontroller (S08LC sub-family) with 36KB on-chip Flash, an integrated LCD controller, and a 40-MHz CPU core, packaged in a 64-pin LQFP (10x10 mm). It targets battery-powered and handheld applications requiring an integrated segment-LCD driver combined with the low-power capabilities of the S08 platform. An HCS08 microcontroller is a member of the 8-bit MCU category that uses the HC08 instruction set with extensions for low-power operation and on-chip peripherals; within the power management taxonomy, an 8-bit MCU belongs to the broader microcontroller > embedded controller > semiconductor device hierarchy. The MC9S08LC36LH combines CPU, memory (Flash + RAM), analog (ADC), communications (SCI/SPI/I2C), and LCD driving in a single chip, reducing external component count for cost-sensitive LCD human-machine-interface designs. Key features confirmed from the verified datasheet extract include 40 MHz maximum CPU clock, 36 KB program Flash, an integrated LCD controller (the defining differentiator of the S08LC sub-family), 18 general-purpose I/O ports, and a 1.8V to 3.6V supply-voltage operating range. The device is specified for the LFQP / LQFP-64 (10 mm x 10 mm, 0.5 mm pitch, 1.40 mm height) package and is described as the first LCD S08 8-bit MCU in NXP's (formerly Freescale) portfolio aimed at battery-powered and handheld segments. Architecturally, the S08LC integrates an HC08-compatible core augmented with a Background Debug mode (BGND) instruction, a Background Debug System (BDS) for in-circuit debugging, and breakpoint capability to allow single breakpoint setting during in-circuit debugging. On-chip peripherals typically found in the family include timers (TPM), real-time interrupt, ADC, and multi-master I2C plus SPI and SCI for asynchronous/synchronous serial. Typical applications include battery-powered handheld instruments (medical meters, remote controls, utility readers), segment-LCD display modules (appliance controls, thermostats, point-of-sale terminals), and consumer / industrial HMI where a single-chip LCD + MCU solution reduces BOM. Its 1.8V minimum supply supports single-cell Li-primary or 2x AA Alkaline chemistries. When designing with this MCU, careful decoupling (100 nF + bulk) is required near each VDD/VSS pair, and the LCD segment/Common pins require proper bias-resistor networks (typically a resistor ladder or charge-pump-based bias generation) to achieve specified contrast and low-quiescent LCD waveforms.
