10 / 111 page GENERAL RELEASE SPECIFICATION INTRODUCTION Rev. 1.0 8 2 3 4 5 6 7 8 9 10 11 12 13 14 A 16 17 18 19 20 SECTION 1 INTRODUCTION 1.1 Introduction The Motorola MC68HC805P18 microcontroller is a member of the M68HC05 microcontroller family with a 4-channel, 8-bit analog-to-digital (A/D) converter, a 16-bit timer with output compare and input capture, a serial communications port (SIOP), a computer operating properly (COP) watchdog timer, and 21 input/output (I/O) pins (20 bidirectional, one input-only). The memory map contains 192 bytes of RAM, 8064 bytes of program EEPROM (for user code), 512 bytes of boot ROM, and128 bytes of EEPROM (for data storage). This device is available in a 28-pin dual in-line package (DIP) or a small outline (SOIC) package. A functional block diagram of the MC68HC805P18 is shown in Figure 1-1. 1.2 Features • Low-cost HC05 core running at 2 MHz bus speed • 28-pin DIP or SOIC package • 4 MHz on-chip crystal/ceramic resonator oscillator • 8064 bytes of user EEPROM including 48 bytes of page zero EEPROM and 16 bytes of user vectors • 192 bytes of on-chip RAM • 128 bytes of EEPROM • Low-voltage reset • 4-channel, 8-bit A/D converter • SIOP serial communications port • COP watchdog timer with active pulldown on RESET • 16-bit timer with output compare and input capture • 20 bidirectional I/O lines and one input-only line • High current sink and source on two I/O pins (PC0 and PC1) Freescale Semiconductor, Inc.
