1. OUTLINE
1.1 Features
Ultra-low power consumption technology
 VDD = single power supply voltage of 1.8 to 5.5 V which
can operate at a low voltage
 HALT mode
 STOP mode
 SNOOZE mode
RL78 CPU core
 CISC architecture with 3-stage pipeline
 Minimum instruction execution time: Can be changed
from high speed (0.04167 s: @ 24 MHz operation with
high-speed on-chip oscillator) to ultra-low speed (1 s:
@ 1 MHz operation)
 Address space: 1 MB
 General-purpose registers: (8-bit register x 8) x 4 banks
 On-chip RAM: 256 B to 2 KB
DMA (Direct Memory Access) controller Note
 2 channels
 Number of clocks during transfer between 8/16-bit SFR
and internal RAM: 2 clocks
Multiplier and divider/multiply-accumulator
 16 bits x 16 bits = 32 bits (Unsigned or signed)
 32 bits x 32 bits = 32 bits (Unsigned)
 16 bits x 16 bits + 32 bits = 32 bits (Unsigned or
signed)
Serial interface
 CSI
 UART
 Simplified I2C communication
 I2C communication
: 1 to 3 channels
: 1 to 3 channels
: 0 to 3 channels
: 1 channel
Code flash memory
 Code flash memory: 2 to 16 KB
 Block size: 1 KB
 Prohibition of block erase and rewriting (security
function)
 On-chip debug function
 Self-programming (with flash shield window function)
Data flash memory Note
 Data flash memory: 2 KB
 Back ground operation (BGO): Instructions are
executed from the program memory while rewriting the
data flash memory.
 Number of rewrites: 1,000,000 times (TYP.)
 Voltage of rewrites: VDD = 1.8 to 5.5 V
High-speed on-chip oscillator
 Select from 24 MHz, 16 MHz, 12 MHz, 8 MHz, 6 MHz,
4 MHz, 3 MHz, 2 MHz, and 1 MHz
 High accuracy: +/- 1.0 % (VDD = 1.8 to 5.5 V, TA = -20
to +85 °C)
Operating ambient temperature
 TA = -40 to +85 °C (A: Consumer applications, D:
Industrial applications)
 TA = -40 to +105 °C (G: Industrial applications) Note
Timer
 16-bit timer
: 4 to 8 channels
 12-bit interval timer : 1 channel
 Watchdog timer : 1 channel (operable with the
dedicated low-speed on-chip
oscillator)
A/D converter
 8/10-bit resolution A/D converter (VDD = 1.8 to 5.5 V)
 8 to 11 channels, internal reference voltage (1.45 V),
and temperature sensor Note
I/O port
 I/O port: 18 to 26
(N-ch open drain I/O [withstand voltage of 6 V]: 2,
N-ch open drain I/O [VDD withstand voltage]: 4 to 9)
 Can be set to N-ch open drain, TTL input buffer, and
on-chip pull-up resistor
 Different potential interface: Can connect to a 1.8/2.5/3
V device
 On-chip key interrupt function
 On-chip clock output/buzzer output controller
Others
 On-chip BCD (binary-coded decimal) correction circuit
Power management and reset function
 On-chip power-on-reset (POR) circuit
 On-chip voltage detector (LVD) (Select interrupt and
reset from 12 levels)
Note Can be selected only in HS (high-speed main) mode.
