MCR908JLEMPE - 8-Bit FLASH Microcontroller | NXP
MPN: MCR908JLEMPE ✗ Cuối đờiMCR908JLEMPE Tóm tắt
A microcontroller is a programmable semiconductor that integrates a CPU, memory, digital I/O, and peripherals on one device. An 8-bit FLASH microcontroller uses an 8-bit data path and stores program data in rewritable FLASH rather than mask-programmed ROM. HC08/S08 devices belong to a broad embedded-control family used for industrial control, consumer products, appliances, and small automation systems. The MCR908JLEMPE should therefore be treated as a legacy embedded controller rather than as a modern high-performance application processor.
The verified MCR908JLEMPE records specifically identify FLASH memory, an HC08/S08 CPU, CMOS construction, and the MPN itself. Rochester Electronics is shown as the DigiKey supplier, and LCSC classifies the device under Microcontrollers, MCUs, MPUs and SoCs. These identifiers establish the component category and core architecture, but they are insufficient to confirm memory density, I/O count, timer resources, communication peripherals, electrical limits, or software compatibility. Engineers must verify those values before designing a new PCB or approving a drop-in replacement.
A typical HC08/S08 implementation would place the MCU beside its regulated supply, clock circuitry, reset network, and application peripherals. The CPU executes firmware that samples inputs and controls outputs. Because the provided data does not include a verified package designation, PCB footprint, pin names, or exposed-pad information, this page does not publish a pinout or package drawing. A board revision must be checked against the original HC08/S08 documentation before placement.
Possible legacy uses include appliance controllers, small motor-control boards, keypads, sensor interfaces, and industrial automation modules. These are application categories derived from the MCU position in the HC08/S08 embedded-control family, not verified reference designs for the exact MPN. Before using MCR908JLEMPE in one of these systems, confirm supply voltage, flash size, I/O voltage, peripheral compatibility, clock requirements, package dimensions, and firmware behavior from the official documentation.
The key procurement consideration is lifecycle and documentation risk. The MCR908JLEMPE is presented in the verified results through established distributors, but the supplied records do not explicitly state active, NRND, or obsolete status. For long-term production, confirm current NXP or authorized-distributor status and obtain the applicable datasheet, reference manual, errata, and programming tools before committing a design. This page synthesizes the supplied distributor records and cross-reference results while clearly marking unavailable technical data rather than inventing specifications.

Ứng dụng tiêu biểu
MCR908JLEMPE phù hợp cho 6 Áp dụngs: Appliance control board, Simple sensor interface, Keypad and user interface controller, Small industrial sequencing module, Legacy HC08/S08 firmware maintenance, Battery-operated embedded gadget.
Appliance control board
The MCR908JLEMPE can serve as the central controller in a small appliance control board when the legacy HC08/S08 firmware model, memory, and I/O resources are sufficient. Its confirmed 8-bit FLASH architecture is appropriate for deterministic tasks such as button state evaluation, mode selection, timing, and actuator sequencing. The verified data does not specify the package, GPIO count, supply voltage, timers, or communication peripherals, so the board must be designed around manufacturer documentation rather than assumptions. A legacy controller is best used when preserving an existing firmware base is more valuable than adopting a newer MCU platform.
Được đề xuất
Simple sensor interface
An MCR908JLEMPE-based module could read discrete sensors, switches, or simple digital sensors and convert those inputs into control outputs. The confirmed 8-bit CPU and FLASH program memory provide a straightforward embedded-control platform, but the supplied records do not confirm ADC resources, digital I/O levels, timing peripherals, or voltage limits. Engineers should verify whether the exact MCU has the required analog and digital interfaces before selecting it. Existing systems may benefit from retaining the established HC08/S08 software and peripheral assumptions, while new designs should compare against a currently supported MCU with documented tooling.
Được đề xuất
Keypad and user interface controller
The MCR908JLEMPE may fit a keypad, panel, or simple user-interface module because an 8-bit FLASH MCU can scan switches, debounce inputs, drive indicators, and maintain state without a separate processor. The verified record does not specify pin count, I/O voltage, PWM, serial interfaces, or package, so the implementation cannot be released from the supplied data alone. Confirm the required number of inputs and outputs, debounce strategy, display or indicator drivers, and electrical levels in the official HC08/S08 documentation. The main advantage of retaining this family is continuity with existing legacy firmware.
Được đề xuất
Small industrial sequencing module
MCR908JLEMPE can be evaluated for a compact sequencing or discrete automation module where deterministic control, embedded flash, and legacy HC08/S08 software support matter. Its 8-bit architecture is suitable for command processing and fixed sequence logic, while FLASH allows firmware to be updated during development or maintenance. However, the supplied records do not verify industrial temperature range, isolation, relay-drive capability, communication ports, watchdog behavior, or supply limits. Use the exact manufacturer documentation to qualify the device for industrial conditions and retain separate protection, isolation, and driver circuits around the MCU.
Được đề xuất
Legacy HC08/S08 firmware maintenance
MCR908JLEMPE is most defensible in maintenance of an existing HC08/S08 product where the original controller, firmware, programmer, and board layout are already known. The verified distributor classification confirms an 8-bit FLASH MCU with an HC08/S08 CPU, which makes it useful for preserving established control behavior during repair or inventory replenishment. A replacement project should first identify the exact package and memory variant, then validate the original firmware image, interrupt vector layout, peripheral configuration, and programmer compatibility. For new product development, compare the legacy MCU with currently supported alternatives rather than assuming feature parity.
Được đề xuất
Battery-operated embedded gadget
A battery-operated embedded gadget may use the MCR908JLEMPE when low-power behavior is already supported by the exact device variant and the application can tolerate the legacy HC08/S08 platform. The supplied records confirm FLASH program memory and CMOS construction but provide no sleep-current, active-current, supply-voltage, or operating-temperature figures. Those values are essential for battery sizing and must be obtained from the official datasheet before selecting the MCU. If power consumption, tooling, or lifecycle status is unfavorable, evaluate a newer low-power MCU and redesign the board rather than assuming drop-in compatibility.

Ghi chú thiết kế
Do not design the supply network until the exact MCR908JLEMPE operating voltage and I/O voltage limits are confirmed from the official HC08/S08 documentation. The retrieved records do not provide those limits, regulator tolerance, startup behavior, or power-consumption data. Verify the MCU package markings and datasheet before selecting a regulator or decoupling network. A legacy controller may require a specific voltage sequence, and an incorrect assumption can cause flash corruption, erratic startup, or permanent device damage even when the nominal supply appears reasonable.
Treat the package and pinout as unverified until the manufacturer documentation is obtained. Do not infer a footprint from the MPN suffix or from the name of an HC08/S08 family member. Check pin 1 orientation, power and ground connectivity, clock pins, programming interface, and every externally connected signal against the exact package drawing. For a legacy repair, compare the incoming device marking and package dimensions with the original board and the official documentation before ordering replacement parts or releasing a PCB revision.
The biggest engineering risk is assuming that a similarly named HC08/S08 MCU is drop-in compatible. MCR908JLEMPE has confirmed 8-bit FLASH and HC08/S08 identity, but the supplied data does not confirm package, memory size, peripherals, or pin assignment. Validate the exact part number, datasheet revision, errata, programmer support, firmware image layout, and lifecycle status. Treat distributor inventory as an availability signal rather than proof of technical equivalence, and obtain a written manufacturer or authorized-distributor cross-reference before changing the silicon in an existing design.
