Introduction
The MC68HC908MR8 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCU). 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 MC68HC908MR8 include:
• High-performance M68HC08 architecture
• Fully upward-compatible object code with M6805, M146805, and
M68HC05 Families
• 8-MHz internal bus frequency
• 8 Kbytes of on-chip FLASH
• On-chip programming firmware for use with host personal
computer
• 256 bytes of on-chip random-access memory (RAM):
• 12-bit, 6-channel center-aligned or edge-aligned pulse-width
modulator (PWMMC)
• Serial communications interface module (SCI)
• Two 16-bit, 2-channel timer interface modules (TIMA and TIMB)
• Eight high current sink and source pins (PTA1/ATD1, PTA0/ATD0,
PTB6/TCH1B, PTB5/TCH0B, PTB4/TCH1A, PTB3/TCH0A,
PTB2/TCLKA, and PTB1/TxD)
• Clock generator module (CGM)
• Digitally filtered low-voltage inhibit (LVI), software selectable for
±5 percent or ±10 percent tolerance
• 10-bit, 4 to 7-channel analog-to-digital converter (ADC)
• System protection features:
– Optional computer operating properly (COP) reset
– Low-voltage detection with optional reset
– Illegal opcode detection with optional reset
– Illegal address detection with optional reset
– Fault detection with optional PWM disabling
• Available packages:
– 32-pin low-profile quad flat pack (LQFP)
– 28-pin dual in-line package (PDIP)
– 28-pin small outline package (SOIC)
• Low-power design, fully static with stop and wait modes
• Break (BRK) module allows single breakpoint setting during
in-circuit debugging
• Master reset pin and power-on reset (POR)
Features of the CPU08 include:
• Enhanced HC05 programming model
• Extensive loop control functions
• 16 addressing modes (eight more than the M68HC05)
• 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
• C language support
