OVERVIEW DESCRIPTION
1.1 Introduction
The MC68F375 is a member of the MC68300/68HC16 family of modular microcontrol-
lers. This family includes a series of modules from which numerous microcontrollers
(MCU’s) are derived. These modules are connected on-chip via the intermodule bus
(IMB). This section includes a list of pins that are available to each module on the chip,

Modular architecture.
32-bit 68000 family CPU with upward object code compatibility (CPU32):
— Virtual memory implementation.
— Loop mode for instruction execution.
— Improved exception handling for controller applications.
— Table lookup and interpolate instruction.
Single chip integration module (SCIM2E):
— External bus support.
— Parallel ports option on address and data bus in single chip modes and par-
tially expanded modes.
— Nine programmable chip select outputs.
— Two special emulation-specific chip select outputs.
— System protection logic.
— System clock based on slow (~32 KHz) or Fast (~4 MHz) crystal reference or
external clock operation (2X).
— Periodic interrupt timer, watchdog timer, clock monitor and bus monitor.
10-bit queued analog-to-digital converter with AMUX (QADC64):
— Up to 16 channels on the QADC64 (25 total including the 16 AMUX Channels).
— 4 automatic channel selection and conversion modes.
— 2 channel scan queues of variable length.
— 64 result registers and 3 result alignment formats.
— Programmable input sample time.
— Analog multiplexer capable of multiplexing 16 analog channels.
Queued serial multi-channel communication module with three serial I/O sub-
systems (QSMCM):
— 2 enhanced SCI (UART): modulus baud rate generator, parity. One SCI has
16 level Rx and Tx queues.
— Queued SPI: 160-byte RAM, up to 32 automatic transfers, continuous cycling,
8-to-16 bits per transfer, LSB/MSB first.
