MC908LD64IFUE 概要
An 8-bit microcontroller (MCU) is a single-chip processor with an 8-bit data path, on-chip program and data memory, and integrated peripherals. The MC908LD64IFUE belongs to the HC08 family (hypernyms: 8-bit microcontroller -> microcontroller -> embedded processor -> semiconductor IC), which uses a von Neumann architecture with a common program/data address space and a simplified instruction set optimized for C-language embedded development. Within that family, the 'LD' sub-family adds a built-in LCD driver, eliminating the need for an external segment-driver IC and reducing BOM cost for meter, thermostat, and white-goods designs.
Key features of the MC908LD64IFUE include 60KB Flash program memory (in-application reprogrammable via the monitor ROM), 2KB SRAM, an internal oscillator that removes the external crystal requirement, 39 GPIO pins, a multi-channel 10-bit ADC, and a sophisticated on-chip LCD controller supporting up to 144 segment outputs. The integrated low-voltage inhibit (LVI), computer-operating-proper (watchdog) timer, and clock generator modules further reduce external component count for cost-sensitive designs.
Architecturally, the HC08 core uses a 16-bit stack pointer with an 8-bit accumulator-based ALU, supports 16-bit BTB signal extensions for LCD timing, and includes a security feature that prevents unauthorized Flash readout. The Flash memory is organized as 60K x 8 with in-circuit programming support through the standard HC08 background debug module (BDM).
Typical applications include white-goods control boards, electronic thermostats, simple metering panels, and battery-powered handheld instruments. Its small footprint and integrated LCD drive make it especially attractive for cost-driven HMI designs.
When designing with this device, verify the LCD segment count, bias, and frame frequency requirements against the on-chip LCD driver configuration registers. Decoupling and PCB layout should follow standard HC08 guidelines, with short, direct traces from the VDD/VSS pins to bulk and ceramic decoupling capacitors.

主な用途
MC908LD64IFUE の用途: 6 件s: White Goods Control Board, Electronic Thermostat, Industrial Metering Panel, Battery-Powered Handheld Instrument, Home Appliance User Interface, Automotive Dashboard Cluster (Legacy).
White Goods Control Board
The MC908LD64IFUE's integrated 144-segment LCD driver eliminates the external segment-driver IC normally required for washing-machine and dishwasher front-panel displays. With 60 KB of Flash it accommodates full state-machine firmware plus menu logic, while 39 GPIO lines handle keypad scanning, relay drivers, and triac control. The internal 6 MHz oscillator removes the external crystal, reducing BOM and assembly cost in high-volume appliance manufacturing.
おすすめ
Electronic Thermostat
Battery-powered thermostats benefit from the MC908LD64IFUE's HC08 low-power modes and integrated LCD segment driver. The device can directly drive a 3-4 common x 32-48 segment LCD for temperature and mode readouts without an external charge pump. Its 39 GPIO lines read temperature sensor inputs, drive relay outputs for HVAC control, and interface to user buttons. The 2 KB RAM is sufficient for set-point storage and scheduling logic.
おすすめ
Industrial Metering Panel
Energy and water metering panels require a robust MCU with LCD segment drive and long-term reliability. The MC908LD64IFUE's 60 KB Flash holds metering firmware, calibration tables, and tariff schedules, while the integrated LCD controller drives multi-digit consumption displays directly. The on-chip watchdog timer and LVI module ensure reliable operation in electrically noisy industrial environments.
おすすめ
Battery-Powered Handheld Instrument
The MC908LD64IFUE's HC08 STOP and WAIT modes enable low quiescent power consumption, extending battery life in handheld measurement instruments. The integrated LCD driver eliminates a separate charge-pump IC, further reducing sleep current. With 60 KB Flash and 2 KB RAM, the device supports rich measurement firmware, data logging, and multi-line segment LCD readouts for portable multimeter-type applications.
おすすめ
Home Appliance User Interface
Microwave ovens, refrigerators, and other home appliances use the MC908LD64IFUE to combine segment-LCD display driving with keypad scanning and appliance control. The 39 GPIO directly drive LEDs, key matrix, and buzzer outputs without external logic. The 64-QFP package fits standard appliance control board footprints, allowing direct migration between appliance product lines with minimal hardware changes.
おすすめ
Automotive Dashboard Cluster (Legacy)
Although the MC908LD64IFUE is not AEC-Q100 qualified, its integrated LCD segment driver is used in legacy non-safety automotive dashboard cluster designs. The HC08 core handles odometer, trip computer, and warning indicator readouts on segment LCDs. For new automotive designs, migrate to AEC-Q100-qualified S08 or Kinetis E LCD MCUs in equivalent QFP packages for ISO 26262 compliance.

主な差別化要因
- Integrated 144-segment LCD driver （vs MC908GR60ACFUE)
- Largest Flash memory in HC08 LCD family （vs MC908GZ32VFUE)
- Lower power modes with LCD retention （vs MC908AZ32AVFU)
設計ノート
Place the VDD and VSS pins with bulk tantalum and ceramic decoupling capacitors (typically 100 nF X7R ceramic in parallel with 10 uF tantalum) within 5 mm of the respective MCU pins. The 64-QFP exposed paddle-style die pad on QFP variants is not present here; use a solid ground pour on the top layer to improve thermal dissipation and EMI immunity for the LCD bias lines.
The HC08 core supports STOP and WAIT low-power modes for battery-powered LCD applications. Configure the LCD charge pump enable and segment bias before entering STOP to allow the LCD to retain its display during MCU sleep. Average quiescent current in STOP with LCD enabled is critical for battery-life estimation and should be measured on the target hardware rather than relying on typical datasheet figures.
When migrating between LD, GZ, GR, AZ, and JL variants, verify pinout compatibility because peripheral pin assignments differ even within the same 64-QFP package. The LCD segment pins on the LD64 are remapped to CAN or GPIO on the AZ/GR/JL families, so firmware developed for one variant will not run unmodified on another. Use the cross-reference tool or pinout spreadsheet before board respins.
