Features
■ 32-bit RX CPU core
Max. operating frequency: 32 MHz
Capable of 49 DMIPS in operation at 32 MHz
Accumulator handles 64-bit results (for a single
instruction) from 32- × 32-bit operations
Multiplication and division unit handles 32- × 32-bit
operations (multiplication instructions take one CPU
clock cycle)
Fast interrupt
CISC Harvard architecture with 5-stage pipeline
Variable-length instructions, ultra-compact code
On-chip debugging circuit
■ Low-power design and architecture
Operation from a single 1.62-V to 5.5-V supply
1.62-V operation available (at up to TBD MHz)
Three low-power modes
■ On-chip flash memory for code, no wait states
32-MHz operation, 31.25-ns read cycle
No wait states for reading at full CPU speed
Up to 256-Kbyte capacity
User code programmable via the SCI
Programmable at 1.62 V
For instructions and operands
■ On-chip data flash memory
8 Kbytes (Number of times of reprogramming: 100,000)
Erasing and programming impose no load on the CPU.
■ On-chip SRAM, no wait states
Up to 16-Kbyte size capacity
■ DMA
DMAC: Incorporates four channels
DTC: Four transfer modes
■ ELC
Module operation can be initiated by event signals
without going through interrupts.
Modules can operate while the CPU is sleeping.
■ Reset and supply management
Seven types of reset, including the power-on reset (POR)
Low voltage detection (LVD) with voltage settings
■ Clock functions
Frequency of external clock: Up to 20 MHz
Frequency of the oscillator for sub-clock generation:
32.768 kHz
On-chip low- and high-speed oscillators, dedicated on-
chip low-speed oscillator for the IWDT
Generation of a dedicated 32.768-kHz clock for the RTC
Clock frequency accuracy measurement circuit (CAC)
■ Real-time clock
Adjustment functions (30 seconds, leap year, and error)
PLQP0100KB-A 14 × 14 mm, 0.5-mm pitch
PLQP0064KB-A 10 × 10 mm, 0.5-mm pitch
PLQP0048KB-A 7 × 7 mm, 0.5-mm pitch
■ Independent watchdog timer
125-kHz on-chip oscillator produces a dedicated clock
signal to drive IWDT operation.
■ Useful functions for IEC60730 compliance
Self-diagnostic and disconnection-detection assistance
functions for the A/D converter, clock-frequency
accuracy-measurement circuit, independent watchdog
timer, functions to assist in RAM testing, etc.
■ Up to seven communications channels
SCI with many useful functions (up to five channels)
Asynchronous mode, clock synchronous mode, smart
card interface mode
I2C bus interface: Transfer at up to 400 kbps, capable of
SMBus operation (one channel)
RSPI (one channel)
■ Up to 14 extended-function timers
16-bit MTU: input capture, output capture,

complementary PWM output, phase counting mode
(six channels)
8-bit TMR (four channels)
16-bit compare-match timers (four channels)
■ 12-bit A/D converter
Capable of conversion within 1.56 μs
Self-diagnostic function and analog input disconnection
detection assistance function
■ Analog comparator
■ General I/O ports
5-V tolerant, open drain, input pull-up, switching of
driving ability
■ MPC
Multiple locations are selectable for I/O pins of
peripheral functions
■ Operating temp. range
40C to +85C
