MC908AS60ACFUE-FR - 8-Bit HC08 MCU 60KB Flash 64-QFP | NXP
MPN: MC908AS60ACFUE-FR ✗ Cuối đờiMC908AS60ACFUE-FR Tóm tắt
An 8-bit microcontroller is a microprocessor integrated with FLASH program memory, RAM, timers, serial communication peripherals, and I/O on a single die. The HC08 is Freescale/NXP's 8-bit core family that succeeded the HC05 and offers an enhanced instruction set, on-chip FLASH, and a more modular peripheral architecture. MCUs such as the MC908AS60ACFUE-FR sit at the bottom of the embedded computing hierarchy: microcontroller -> embedded processor -> semiconductor IC. They are designed for deterministic, low-power control loops where 32-bit performance is unnecessary.
Key features of this device include 60KB (60K x 8) of FLASH, 2KB (2K x 8) of RAM, 52 general-purpose I/O lines, an internal oscillator, and on-chip peripherals that typically include a timer/PWM module, an 8-channel 8-bit ADC, SCI and SPI serial interfaces, and a CAN 2.0B controller (consistent with the AS-series HC08 family). The 64-QFP (14x14) footprint is a widely-used through-hole-friendly surface-mount package that simplifies PCB layout and rework.
The MC908AS60ACFUE-FR uses a von-Neumann bus architecture with the HC08 CPU core, an on-chip bandgap reference, low-voltage detect (LVD) and power-on reset (POR) for robust startup, and a system integration module that maps peripherals into a single linear address space. Peripherals are clock-gated to minimize quiescent current, and the internal clock source eliminates the external crystal in many designs.
Typical applications include automotive body controllers (door modules, seat controllers, HVAC blowers), industrial PLCs and sensor transmitters, white-goods and appliance motor control, security alarm panels, and battery-powered metering. The wide temperature range and integrated CAN bus support also suit automotive networks and 12V/24V industrial systems.
Designers should note that the -FR suffix typically denotes factory-reel packaging and identical die to the non-FR variant, so firmware and software are fully portable. This part is widely available through authorized distributors; users designing new products should verify the current lifecycle status with NXP, as the HC08 family is in mature / last-time-buy phase at many suppliers.

Ứng dụng tiêu biểu
MC908AS60ACFUE-FR phù hợp cho 6 Áp dụngs: Automotive Body Control Module, Industrial Sensor Transmitter / PLC, White-Goods Appliance Motor Control, Security Alarm / Access Control Panel, Battery-Powered Smart Metering, HVAC / Building Automation Controller.
Automotive Body Control Module
The MC908AS60ACFUE-FR's 60 KB FLASH and 2 KB RAM are well matched to automotive body controllers for door modules, seat controllers, mirror adjusters, and HVAC blowers. The integrated MSCAN (CAN 2.0B) controller supports up to 1 Mbit/s communication on the vehicle body bus, allowing direct connection to BCM gateway ECUs without an external CAN transceiver microcontroller. Its 52 GPIO lines drive relays, H-bridges and LED matrices directly, while the on-chip 8-channel ADC reads seat-position sensors, temperature probes, and current shunts. Compared with newer S08 parts the HC08AS has 8.4 MHz bus speed, sufficient for low-rate body tasks. Wide operating voltage (typically 5 V) suits 12-V-battery-powered nodes with simple LDO regulation.

Industrial Sensor Transmitter / PLC
The MC908AS60ACFUE-FR is a good fit for industrial 4-20 mA loop-powered sensor transmitters and small PLCs because the HC08AS-AZ core combines deterministic 8.4 MHz execution with on-chip 8-bit ADC, SCI, SPI, and PWM channels in a single 64-QFP package. The internal oscillator eliminates a crystal in many designs, lowering BOM cost. The wide HC08 supply tolerance tolerates 24 V industrial rails after a simple LDO pre-regulator. CANbus connectivity enables fieldbus bridging. Compared with a 32-bit Cortex-M0, the 8-bit part is cheaper and more power-efficient for simple scaling, linearization, and HART-modem tasks; firmware fits within 60 KB FLASH with no external bus required.

White-Goods Appliance Motor Control
Washing machines, dishwashers, and refrigerators use the MC908AS60ACFUE-FR to drive BLDC and single-phase AC induction motors via on-chip PWM and timer modules. The 60 KB FLASH holds sensorless or back-EMF commutation tables plus user-interface state machines, while 2 KB RAM suffices for runtime commutation buffers. The HC08AS-AZ family is designed for 5 V supply with internal regulator options, simplifying SMPS-for-motor design. Compared with a discrete MCU + gate-driver pair, this part reduces PCB area. Its industrial temp grade and integrated CAN connectivity support modern connected appliances that report status to a master HMI controller.

Security Alarm / Access Control Panel
Security alarm panels benefit from the MC908AS60ACFUE-FR's low-power HC08 core, integrated SCI/SPI for keypad and GSM/GPRS modem links, and 52 GPIO for zone inputs and siren drivers. The 60 KB FLASH stores zone-event logs and dialer protocols while 2 KB RAM buffers keypad scans. Wide supply tolerance handles backup-battery charging scenarios from 12 V SLA cells via simple LDO. Compared with a 32-bit Cortex MCU, the HC08AS-AZ offers lower BOM cost and easier EMC compliance due to slower edge rates. The internal oscillator reduces part count for cost-sensitive residential panels.

Battery-Powered Smart Metering
Electricity, gas, and water meters use the MC908AS60ACFUE-FR for metrology, LCD drive, and wireless M-Bus / wireless M-Bus / KNX / LoRaWAN bridging thanks to the HC08AS-AZ's low quiescent current and integrated LCD driver option in the same 64-QFP package. The 60 KB FLASH holds segmented LCD font tables and tariff schedules; 2 KB RAM buffers rolling consumption logs. The on-chip 8-channel ADC reads CT shunts or temperature sensors. Compared with discrete metering solutions, integration cuts BOM by 30-40%. The NRND status means designers should plan S08 or S12 migration; existing field-deployed units can be sustained with Rochester Electronics stock.
Được đề xuất
HVAC / Building Automation Controller
Commercial HVAC and building-automation controllers use the MC908AS60ACFUE-FR to run PID loops on temperature, humidity, and air-quality sensors while driving triacs and relays through 52 GPIOs. The integrated CANbus and SCI ports support BACnet MS/TP, N2, and Modbus fieldbus networks; SPI links to external radio modules for wireless nodes. The 60 KB FLASH holds PID, scheduling, and fault-diagnostic firmware with headroom for OTA bootloader. Compared with a 32-bit MCU, the HC08AS-AZ offers deterministic interrupt latency and better EMC at lower cost. The -FR factory reel supports high-volume SMT production.

Ghi chú thiết kế
The HC08AS-AZ core typically operates from a single 5 V (or 3.3 V) VDD rail with on-chip voltage regulator. Add a 100 nF decoupling capacitor on each VDD/VSS pair as close to the package as possible, plus a bulk 10 uF tantalum or ceramic on the main supply pin. The internal oscillator can be bypassed with an external crystal on OSC1/OSC2; route these traces short and guard with a ground ring to reduce EMI. Estimated: a typical HC08AS design running at 8.4 MHz draws 15-25 mA active and under 50 uA in STOP mode.
The 64-QFP (14x14 mm) package has a 0.8 mm lead pitch, which is manageable with standard SMT processes but requires careful pad design (use the IPC-7351 nominal footprint with 0.4 mm-wide pads). Allow at least 5 mm of keep-out under the QFP body for probe access during BDM debug. Route CANH/CANL as a 120-ohm-impedance differential pair with a split termination at each end; keep SCI/SPI traces matched in length to avoid skew on multi-drop buses.
Three common pitfalls: (1) Always assert RST low at power-up until VDD crosses the LVD threshold - leaving RST floating can cause undefined code execution. (2) The PTH0/PTH1 pins may be shared with the MODC / MODB mode-select pins at reset - do not pull them to arbitrary levels or the MCU may enter a special test mode instead of normal single-chip mode. (3) The VPP pin should be left open or tied to VDD in run mode; only drive it during FLASH programming via the BDM/MON08 interface.
At 8.4 MHz the HC08AS-AZ typically dissipates well under 200 mW, so the 64-QFP package does not require a heatsink or thermal via array. However, in sealed automotive under-hood environments verify the junction temperature against the datasheet thermal resistance (theta_JA typically 50-60 C/W for QFP-64 on a 4-layer JEDEC test board). Estimated: at 85 C ambient the junction stays below 100 C with conservative 100 mA active current.
