MC908GZ60MFAE 概述
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/FLASH), working memory (RAM), I/O peripherals, and timers on a single silicon die. The HC08 architecture sits in the 'low-cost, high-performance' tier of 8-bit MCUs and is fully compatible with legacy M68HC05 object code, allowing reuse of mature codebases in new designs. Within the broader taxonomy, the MC908GZ60MFAE belongs to microcontroller -> embedded processor -> semiconductor device family.
Key features include 60KB of FLASH for application code, 2KB of RAM for stack and variables, 8 MHz internal bus frequency derived from an internal oscillator, 37 I/O pins, and a maximum of up to 24 channels of 10-bit ADC (per family datasheet). The device operates from a single 3.0V to 5.5V supply, simplifying power-tree design. The 48-LQFP package exposes enough pins for typical embedded roles while remaining hand-solderable for prototyping and low-volume production.
Technically, the CPU08 core is an enhanced M68HC08 implementation with additional indexed addressing modes and a stack-pointer paging feature that improves C-compiler efficiency. The on-chip FLASH supports in-application reprogramming via the standard HC08 monitor ROM, enabling firmware updates in the field. The internal oscillator can be trimmed at the factory, removing the need for an external crystal in many cost-sensitive designs and reducing BOM count.
Typical applications include appliance control (washing machines, dishwashers, HVAC control boards), industrial sensor interfaces, low-cost user-interface panels with key scans and LED/PWM drives, automotive body and comfort subsystems, and consumer white-goods main controllers. The combination of FLASH memory, RAM, and 37 I/O suits designs that previously used an HC05 plus external logic.
When designing with this device, note that NXP has published a Discontinuance and Replacement Product Change Notice for the M68HC08 family. Engineers starting new designs should evaluate the suggested NXP replacement families; this page documents the part for legacy maintenance and stock replenishment support only.
This page synthesizes current distributor pricing and stock, drop-in NXP same-family alternates, and design considerations not all covered in the original NXP datasheet, providing a single reference for engineers maintaining HC08GZ-based products.

典型应用
MC908GZ60MFAE 适用于 6 应用s: White Goods and Appliance Control, Industrial Sensor Interface Module, Automotive Body and Comfort Subsystems, Low-Cost User Interface Panels, Consumer White-Goods Replacement of HC05 Designs, Battery-Operated Measurement Pods.
White Goods and Appliance Control
The MC908GZ60MFAE's 60 KB FLASH, 2 KB RAM, and 37 GPIO lines fit washing-machine, dishwasher, and HVAC control board roles where deterministic 8-bit scheduling and 5 V tolerance simplify actuator drive. Why this part fits: HC08GZ integrates 10-bit ADC for temperature and water-level sensing plus timer/PWM channels for motor and valve control, eliminating external logic. Performance consideration: at 8 MHz internal bus the C-compiled scheduler leaves ample headroom for keypad scanning, LED multiplexing, and safety-state machines; add a small external watchdog if the appliance needs IEC 60730 class B compliance.
推荐
Industrial Sensor Interface Module
The HC08GZ's up to 24 channels of 10-bit ADC and 37 GPIO suit multi-channel sensor-interface boards reading analog process variables in factory automation. Why this part fits: the 3.0 V to 5.5 V supply tolerates legacy 5 V industrial sensors, while the FLASH size accommodates calibration tables and look-up routines. Performance consideration: at one ADC conversion per channel per scan cycle the 8 MHz CPU still has margin for averaging filters and HMI refresh; place an external precision reference if measurement accuracy below ADC LSB drift is required.
推荐
Automotive Body and Comfort Subsystems
Although not AEC-Q100 qualified by default, the HC08GZ has historically driven seat-control, mirror, and lighting modules within the 8-bit budget tier. Why this part fits: 5 V tolerance matches automotive battery transients within the operating range, and HC08 object-code compatibility eases migration from earlier HC05 designs. Performance consideration: NXP has issued a family PCN; for new automotive designs move to the recommended replacement, using this part only on existing platform maintenance through the last-time-buy window.
推荐
Low-Cost User Interface Panels
Key-scan matrix plus LED/PWM drive plus LCD segment control fit budget HMI panels on industrial equipment. Why this part fits: 37 GPIO can matrix-scan a 4 x 4 keypad with room for status LEDs, and the FLASH stores menu state machines and localization tables. Performance consideration: use timer overflow interrupts to debounce keys and refresh LEDs deterministically; budget RAM for a small display buffer if adding an LCD module, or offload to an external driver IC over SPI if RAM is tight.
推荐
Consumer White-Goods Replacement of HC05 Designs
The CPU08 is fully object-code upward-compatible with M68HC05, making the MC908GZ60MFAE a drop-in upgrade for legacy HC05 firmware with extra FLASH headroom. Why this part fits: existing HC05 object code runs without rewrite; added indexed addressing and stack-pointer paging improve C-compiler efficiency for new modules. Performance consideration: validate interrupt-vector mapping before reusing HC05 firmware since the HC08 vector table is slightly different, and verify all electrical parameters against the new part's datasheet for any I/O pin that previously latched an absolute maximum.
推荐
Battery-Operated Measurement Pods
Battery-powered sensor pods that wake periodically to read sensors and transmit via UART or RF link benefit from the HC08GZ's low active power and small footprint. Why this part fits: the 8 MHz core and integrated ADC wake the part, take a reading, and return to sleep within microamp-average budgets typical of coin-cell designs. Performance consideration: configure the internal oscillator to a slower mode during sleep transitions and gate unused peripherals to extend battery life; for sub-uA standby, augment with an external low-power RTC that wakes the MCU only on schedule.

关键差异点
- Largest on-chip FLASH in the HC08GZ 48-LQFP family （对比 MC908GZ32CFUE)
- Same HC08GZ peripheral set at lower cost than the S08AC128CLK （对比 S08AC128CLK)
- Direct NXP same-family lead-free tray variant （对比 MC908GZ60MFUE)
设计说明
Estimated: The MC908GZ60MFAE draws its supply current from a 3.0 V to 5.5 V rail. Decouple the VDD pins (3 and 47) with a 100 nF ceramic placed within 5 mm of each pin, and add a bulk 10 uF electrolytic on the same node. For designs that transition between 5 V (active) and 3.3 V (battery), include a supervisor such as MAX150ACPP on RST to guarantee a clean power-on reset ramp.
Route the RST line away from PWM and switching traces; keep the RST pull-up network close to the device and place a 100 nF bypass directly across the RST pin to VSS. The 48-LQFP thermal pad is not internally bonded to GND on the HC08 family, so do not attempt to use it as a heatsink or ground stitch - rely on VSS pins 4 and 48 instead.
HC08 object code is upward-compatible with M68HC05, but the interrupt-vector table is not identical. When porting existing HC05 firmware, regenerate the vector table against the HC08GZ datasheet or startup files, and verify all peripherals in the chip-configuration register map. Also confirm the address range of any absolute-addressed I/O register: HC08GZ peripheral addresses are family-specific and not interchangeable with HC05 or HCS08.
