MC9S08LH64CLH - 40MHz 64KB Flash 8-Bit MCU | NXP
MPN： MC9S08LH64CLH ✗ 停產MC9S08LH64CLH 概覽
A microcontroller is a programmable integrated circuit that combines a CPU core, memory, input/output ports, timers, communication interfaces, and analog peripherals on one device. The S08LH family belongs to the 8-bit MCU hierarchy and is intended to provide economical control for metering, medical instrumentation, industrial equipment, and battery-powered products. Rather than relying on multiple discrete components, an MCU centralizes computation, sensing, display control, and system communication.
The verified product information identifies a 40 MHz maximum clock, 64 KB Flash, the S08 CPU core, and a 64-LQFP package. The family also features an LCD driver and increased ADC accuracy for medical and metering applications. Its ultra-low-power design targets energy-efficient operation, while the larger flash capacity provides more room for firmware than smaller members of the S08 family.
The MC9S08LH64CLH is listed as NRND by NXP, meaning it is not recommended for new designs. Existing products may continue to use the device, but engineers should confirm lifecycle status, availability, and long-term sourcing before starting a new production program. The CLH orderable designation identifies a specific package and temperature-grade configuration, so replacement parts should be checked against the complete part-number decoding.
Typical uses include utility meters, medical monitoring equipment, industrial controllers, sensor interfaces, and compact battery-powered instruments. The LCD driver is particularly useful for local alphanumeric or segmented displays, while the ADC supports analog measurement. Firmware should configure the required LCD segments, calibrate analog channels, and validate low-power behavior before deployment.
Designers should follow the manufacturer datasheet for pin multiplexing, clock, decoupling, programming, and electrical limits. Because this is a 64-pin LQFP device, careful fan-out and routing are necessary to reduce assembly risk and preserve analog performance. This page consolidates verified lifecycle, package, memory, and application information while identifying where additional datasheet parameters are required.

典型應用
MC9S08LH64CLH 適用於 6 應用s: Battery-Powered Utility Meter, Medical Monitoring Instrument, Industrial Sensor Interface, Battery-Powered Data Logger, Compact Metering Display Controller, Portable Diagnostic Equipment.
Battery-Powered Utility Meter
The MC9S08LH64CLH fits a compact utility meter where an LCD readout, analog measurement, and low-power operation are required. Its S08LH family is described as ultra-low-power, while the LCD driver reduces the need for separate display-control hardware and the improved ADC accuracy supports measurement channels. A meter design can use the 40 MHz MCU for acquisition, calculation, calibration, and display updates while spending much of its time in a low-power state. The main verification points are battery budget, ADC calibration, LCD contrast, input protection, and the exact operating-temperature limits from the NXP datasheet.
推薦
Medical Monitoring Instrument
The MC9S08LH64CLH can serve as the control MCU in a medical monitoring instrument that combines sensor acquisition, status display, and low-power operation. The verified family information specifically cites increased ADC accuracy and medical applications, while the LCD driver supports a local human-interface display. Firmware can perform signal conditioning, threshold checks, data logging, and alert handling around the 40 MHz S08 core. Because medical products require application-specific validation, engineers must confirm the required accuracy, isolation, safety, and regulatory requirements rather than treating the MCU family description as a complete medical qualification.
推薦
Industrial Sensor Interface
The MC9S08LH64CLH is appropriate for an embedded sensor interface that must acquire analog inputs and present local status without a separate display controller. Its 64 KB Flash provides room for application firmware, drivers, calibration tables, and communications routines, while the LCD driver can show measurement values and operating status. A practical design could use the MCU to scan sensors, filter readings, detect thresholds, and update a segment or character LCD. Industrial suitability still depends on verified supply limits, noise performance, temperature range, watchdog behavior, and the robustness of the external analog front end.
推薦
Battery-Powered Data Logger
The MC9S08LH64CLH can coordinate periodic measurements in a portable data logger where standby power consumption is important. The ultra-low-power S08LH positioning supports duty-cycled operation: the MCU can wake, acquire a reading, update the LCD, store or transmit data, and return to a low-power state. The 40 MHz clock provides headroom for protocol handling and local computation, while 64 KB Flash can hold firmware and fixed parameters. Actual battery life must be calculated from the selected low-power modes, LCD duty cycle, sensor current, leakage, and regulator losses rather than from the maximum clock frequency alone.
推薦
Compact Metering Display Controller
The MC9S08LH64CLH is suitable for the display and control section of a compact metering product because its integrated LCD driver reduces external display-controller overhead. The MCU can manage segment mapping, measurement formatting, button input, alarms, and operating-mode changes while using the S08 core at up to 40 MHz for control logic. For production designs, verify LCD voltage requirements, segment count, bias configuration, and timing from the complete datasheet. Mechanical display selection and PCB routing also matter because a 64-LQFP footprint can constrain panel placement in a compact enclosure.
推薦
Portable Diagnostic Equipment
The MC9S08LH64CLH can be used in portable diagnostic equipment that needs local control, measurement, and a readable display without a high-end processor. The 8-bit S08 core is suited to supervisory and acquisition tasks, and the 64 KB Flash capacity supports embedded firmware for calibration, sequencing, and diagnostics. The improved ADC accuracy is relevant when small analog changes must be resolved reliably, but the application must still define the input range, sample rate, noise requirements, and calibration method. Validation should include sensor settling, ADC reference stability, display update latency, and battery-current measurements.

設計說明
The MC9S08LH64CLH is associated with ultra-low-power S08LH designs, but the final battery life depends on the selected operating mode, LCD load, ADC duty cycle, and external regulator losses. Estimate the average current from the datasheet operating-current and sleep-current figures, then include sensor and display standby current. Do not derive a production power budget from the 40 MHz maximum clock because the maximum frequency is not a continuous operating requirement.
Use the NXP package drawing and recommended layout as the authority for the 64-LQFP footprint. Confirm pin 1 orientation, lead pitch, pad dimensions, solder-mask clearance, and assembly tolerances before releasing artwork. Place decoupling structures close to the appropriate supply pins and provide clean return paths for the LCD and analog sections; the supplied distributor snippets do not specify the complete pinout or electrical limits.
Separate sensitive analog routing from LCD drive and digital switching paths where the board area permits. Keep sensor inputs short and protect them according to the application's ESD and surge requirements. Because the MC9S08LH64CLH includes increased ADC accuracy positioning, layout and grounding should preserve signal integrity; verify the reference, sample-and-hold, and acquisition recommendations in the manufacturer datasheet before finalizing the PCB.
Do not treat a similar NXP S08 MPN as an automatic drop-in replacement. The supplied cross-reference search returned comparison candidates but did not verify their pinout, memory map, LCD resources, ADC behavior, clock tree, or software model. Because MC9S08LH64CLH is NRND, document the existing firmware, timing assumptions, package drawing, and sourcing plan before selecting any successor.
合規資訊
The supplied search results do not provide verified RoHS, REACH, lead-free, halogen-free, or conflict-minerals statements. Compliance must be confirmed from the current NXP product documentation and applicable distributor declarations.
