Data Sheet MC68HC908RF2 Section General Description Introduction The MC68HC908RF2 MCU is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units MCUs . Optimized for low-power operation and available in a small 32-pin low-profile quad flat pack LQFP , this MCU is well suited for remote keyless entry RKE transmitter designs. All MCUs in the family use the enhanced M68HC08 central processor unit CPU08 and are available with a variety of modules, memory sizes and types, and package types. Features MCU include • High-performance M68HC08 architecture • Fully upward-compatible object code with M6805, M146805, and M68HC05 Families • Maximum internal bus frequency of 4 MHz at volts • Maximum internal bus frequency of 2 MHz at volts • Internal oscillator requiring no external components Software selectable bus frequencies ± 25 percent accuracy with trim capability to ±2 percent Option to allow use of external clock source or external crystal/ceramic resonator • 2 Kbytes of on-chip FLASH memory • FLASH program memory security 1 • 128 bytes of on-chip RAM • 16-bit, 2-channel timer interface module TIM No security feature is absolutely secure. However, Motorola’s strategy is to make reading or copying the FLASH difficult for unauthorized users. For More Information On This Product, Go to: Data Sheet 15 Freescale Semiconductor, Inc... Freescale Semiconductor, Inc. • 12 general-purpose input/output I/O ports Six shared with keyboard wakeup function Two shared with the timer module Port A pins have 3-mA sink capabilities • Low-voltage inhibit LVI module 1.85-V detection forces MCU into reset 2.0-V detection sets indicator flag • 6-bit keyboard interrupt with wakeup feature • External asynchronous interrupt pin with internal pullup IRQ • Ultra high frequency UHF transmitter • System protection features: Computer operating properly COP reset Low-voltage detection with reset Illegal opcode detection with reset Illegal address detection with reset • 32-pin plastic LQFP package • Low-power design with stop and wait modes • Master reset pin and power-on reset POR • to 85°C and to 125°C operation Features of the CPU08 include • Enhanced HC05 programming model • Extensive loop control functions • 16 addressing modes eight more than the HC05 • 16-bit index register and stack pointer • Memory-to-memory data transfers • Fast 8 x 8 multiply instruction • Fast 16/8 divide instruction • Binary-coded decimal BCD instructions • Optimization for controller applications • Third party C language support MCU Block Diagram Figure 1-1 shows the structure of the MC68HC908RF2 MCU.
