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. The M68HC08 Family is based on the customer-specified integrated circuit (CSIC) design strategy. 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
Features of the MC68HC908RF2 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 3.3 volts
? Maximum internal bus frequency of 2 MHz at 1.8 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)
? 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 (IRQ1)
? 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)
? –40° to 85° Celsius 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 × 8 multiply instruction
? Fast 16/8 divide instruction
? Binary-coded decimal (BCD) instructions
? Optimization for controller applications
? Third party C language support
