General Description
Features
⢠Memory
â 128K byte flash EEPROM, made of four 32K byte modules
with 8K bytes protected BOOT section in each module
â 2K byte EEPROM
â 8K byte RAM with Vstby, made of two 4K byte modules.
⢠Two Analog-to-digital converters
â 2 times 8-channels, 10-bit resolution
⢠Three 1M bit per second, CAN 2.0 A, B software compatible
modules on the MC68HC912DT128A (two on the
MC68HC912DG128A)
â Two receive and three transmit buffers per CAN
â Flexible identifier filter programmable as 2 x 32 bit, 4 x 16 bit or
8 x 8 bit
â Four separate interrupt channels for Rx, Tx, error and wake-up
per CAN
â Low-pass filter wake-up function
â Loop-back for self test operation
â Programmable link to a timer input capture channel, for time-
stamping and network synchronization.
⢠Enhanced capture timer (ECT)
â 16-bit main counter with 7-bit prescaler
â 8 programmable input capture or output compare channels; 4
of the 8 input captures with buffer
â Input capture filters and buffers, three successive captures on
four channels, or two captures on four channels with a
capture/compare selectable on the remaining four
â Four 8-bit or two 16-bit pulse accumulators
â 16-bit modulus down-counter with 4-bit prescaler
â Four user-selectable delay counters for signal filtering
