Descripción
Introduction The MC68HC908BD48 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). 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. The MC68HC908BD48 is designed specifically for use in digital monitor systems. Features Features of the MC68HC908BD48 MCU include the following: • High-performance M68HC08 architecture • Fully upward-compatible object code with M6805, M146805, and M68HC05 families General Description Technical Data MC68HC908BD48 — Rev. 1.0 26 General Description MOTOROLA • Low-power design; fully static with stop and wait modes • 5V operating voltage • 6MHz internal bus frequency; with 24MHz external crystal • 48,128 bytes of on-chip FLASH memory • 1,024 bytes of on-chip random access memory (RAM) • Sync signal processor with the following features: – Horizontal and vertical frequency counters – Low vertical frequency indicator (40.7Hz) – Polarity controlled Hsync and Vsync outputs from separate sync or composite sync inputs – Internal generated free-running Hsync and Vsync pulses – CLAMP pulse output to the external pre-amp chip • 6-channel, 8-bit analog-to-digital converter (ADC) • 16-channel, 8-bit pulse width modulator (PWM) • Full universal serial bus (USB) specification 1.0 compliant lowspeed bus with 3 endpoints: – 1 Control endpoint (two 8-byte buffer) – 2 Interrupt endpoints (one 8-byte buffer shared) • On-chip 3.3V regulator for USB pull-up resistor • DDC12AB1 module with the following: – DDC1 hardware – Multi-master IIC2 hardware for DDC2AB; with dual address • Additional multi-master IIC module • 16-bit, 2-channel timer interface modules (TIM) with selectable input capture, output compare, and PWM capability on one channel • Up to 32 general purpose input/output (I/O) pins, including: – 32 shared-function I/O pin for 42-pin and 44-pin packages 1.
