General Description

Freescale Semiconductor

1.3 Features

Features of the MC68HC908JB16 MCU include the following:

•

High-performance M68HC08 architecture

•

Fully upward-compatible object code with M6805, M146805, and

M68HC05 families

•

Low-power design; fully static with stop and wait modes

•

6-MHz internal bus frequency

•

16,384 bytes of on-chip FLASH memory with security1 feature

•

384 bytes of on-chip random access memory (RAM)

•

Up to 21 general-purpose input/output (I/O) pins, including:

–

15 shared-function I/O pins

–

8-bit keyboard interrupt port

–

10mA high current drive for PS/2 connection on 2 pins

(with USB module disabled)

–

1 dedicated I/O pin, with 25mA direct drive for infrared LED

(32-pin package)

–

6 dedicated I/O pins, with 25mA direct drive for infrared LED

on 2 pins and 10mA direct drive for normal LED on 4 pins

(28-pin package)

•

Two 16-bit, 2-channel timer interface modules (TIM1 and TIM2)

with selectable input capture, output compare, PWM capability on

each channel, and external clock input option (TCLK)

•

Universal Serial Bus specification 2.0 low-speed functions:

–

1.5Mbps data rate

–

On-chip 3.3V regulator

–

Endpoint 0 with 8-byte transmit buffer and 8-byte receive buffer

–

Endpoint 1 with 8-byte transmit buffer

–

Endpoint 2 with 8-byte transmit buffer and 8-byte receive buffer

1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or

copying the FLASH difficult for unauthorized users.
