Introduction
1.1 Features
Features on the MC68HC705KJ1 include:
Robust noise immunity
4.0-MHz internal operating frequency at 5.0 V
1240 Bytes of EPROM/OTPROM (electrically programmable read-only memory/one-time
programmable read-only memory), including eight bytes for user vectors
64 bytes of user RAM
Peripheral modules:
15-stage multifunction timer
Computer operating properly (COP) watchdog
10 bidirectional input/output (I/O) lines, including:
10-mA sink capability on all I/O pins
Software programmable pulldowns on all I/O pins
Keyboard scan with selectable interrupt on four I/O pins
5.5-mA source capability on six I/O pins
Selectable sensitivity on external interrupt (edge- and level-sensitive or edge-sensitive only)
On-chip oscillator with connections for:
–Crystal
Ceramic resonator
Resistor-capacitor (RC) oscillator (MC68HRC705KJ1) with or without external resistor
External clock
Low-speed (32-kHz) crystal (MC68HLC705KJ1)
Memory-mapped I/O registers
Fully static operation with no minimum clock speed
Power-saving stop, halt, wait, and data-retention modes
External interrupt mask bit and acknowledge bit
Illegal address reset
Internal steering diode and pullup resistor from RESET pin to VDD
Selectable EPROM security(1)
Selectable oscillator bias resistor
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or copying the EPROM/OTPROM
difficult for unauthorized users.
