MC9S12C32
Overview
Freescale Semiconductor’s HCS12 family of
microcontrollers (MCUs) is the next generation
of the highly successful 68HC12 architecture.
Using Freescale’s industry-leading, 0.25 µs Flash,
the MC9S12C32 is part of a pin-compatible
family that scales from 32 KB to 128 KB of
Flash memory. The MC9S12C32 provides an
upward migration path from Freescale’s
68HC08, 68HC11 and 68HC12 architectures
for applications that need large memory, many
peripherals and high performance.
Target Applications
> Automotive applications
> Industrial control
Features Benefits
High-Performance 16-bit HCS12 CPU Core
On-Chip Debug Interface
> Single-wire background debug mode
> On-chip trace buffer with nine flexible trigger
modes and multiple hardware breakpoints
> Non-intrusive emulation
> Real-time emulation of MCU functions at full
operating voltage and frequency range with no
limitations like traditional emulators
> Real-time in-circuit emulation and debug
without expensive and cumbersome
box emulators
> Read/write memory and registers while
running at full speed
> Bus state analysis without the expense of a
traditional emulator
Network Module
> One MSCAN module implementing the CAN 0
A/B protocol
• Five receive buffers per module with FIFO
storage scheme
• Three transmit buffers per module with
internal prioritization
> Programmable bit rate up to 1 Mbps
> FIFO receive approach superior for
event-driven networks
Integrated Third-Generation Flash Memory
> In-application reprogrammable
> Self-timed, fast programming
• Fast Flash page erase—20 ms (512 bytes)
• Can program 16 bits in 20 µs while in
burst mode
> 3.3V to 5V Flash program/erase/read
> Flash granularity—512 byte Flash erase/
2 byte Flash program
> Flexible block protection and security
> Flexibility to change code in the field
> Efficient end of line programming
> Total program time for 128 KB code is less
than five seconds
> Reduces production programming cost
through ultra-fast programming
> No external high voltage or charge pump
required
> Virtual EEPROM implementation, Flash array
usable for EE extension
10-bit Analog-to-Digital Converter (ADC)
> One 8-channel ADC
> 7 µs, 10-bit single conversion time; scan
mode available
> Fast, easy conversion from analog
inputs like temperature, pressure
and fluid levels to digital values
for CPU processing
> 25 MHz bus operation at 3.3V to 5V for
40 ns minimum instruction cycle time
> Opcode compatible with the 68HC11
and 68HC12
> C-optimized architecture produces extremely
compact code
Timer Module
> 8-channel timer, each channel configurable as
either input capture or output compare
> Simple pulse width modulation
(PWM) mode
> 16-bit pulse accumulator
> Flexible, programmable
timer system
