Features of the MC68HC908JB8 include:
⢠High-performance M68HC08 architecture
⢠Fully upward-compatible object code with M6805, M146805, and
M68HC05 Families
⢠3-MHz internal bus frequency
⢠8,192 bytes of on-chip FLASH memory
⢠256 bytes of on-chip random-access memory (RAM)
⢠FLASH program memory security1
⢠On-chip programming firmware for use with host PC computer
⢠Up to 37 general-purpose 3.3V input/output (I/O) pins, including:
â 13 or 10 shared-function I/O pins, depending on package
â 24, 8, or 2 dedicated I/O pins, depending on package
â 8 keyboard interrupts on port A, on all packages
â 10mA sink capability for normal LED on 4 pins
â 25mA sink capability for infrared LED on 2 pins
â 10mA sink capability for PS/2 connection on 2 pins
(with USB module disabled)
⢠16-bit, 2-channel timer interface module (TIM) with selectable
input capture, output compare, PWM capability on each channel,
and external clock input option (TCLK)
⢠Full Universal Serial Bus Specification 1.1 low-speed functions:
â 1.5 Mbps data rate
â On-chip 3.3V regulator
â Endpoint 0 with 8-byte transmit buffer and 8-byte receive buffer
â Endpoint 1 with 8-byte transmit buffer
â Endpoint 2 with 8-byte transmit buffer and 8-byte receive buffer
1. No security feature is absolutely secure. However, Freescaleâs strategy is to make reading or
copying the FLASH difficult for unauthorized users.
