SNOOZE mode sequencer (SMS)

• Calculations and comparison of values by the

commands for use in processing by the

sequencer can realize intermittent operations

where the RL78/L23 does not have to return to

normal operation.

• Sequentially handling a total of 32 processes with

the use of desired commands from among 21

different ones

• The SNOOZE mode sequencer offers operation

with low power consumption without using the

CPU, flash memory, and RAM.

Logic and event link controller (ELCL)

• Event signals can be set up between specified

peripheral functions.

• The signals can be generated by the input of

multiple event signals to the logic circuit.

• Flip-flop circuits are incorporated to handle setting

and resetting functions.

Serial interface

• Simplified SPI (CSINote): 5 to 8 channels

• UART/UART (LIN-bus supported)/UARTA: 5 to 8

channels

•I2C/Simplified I2C: 8 to 10 channels

Timers

• 16-bit timer: 8 channels (with the output of remote

control signals)

• 16-bit timer RJ: 1 or 2 channels

• 16-bit timers KB40, KB41, and KB42: 1 to 3

channels (with PWM output for IH)

• 32-bit interval timer:

1 channel in 32-bit counter mode

2 channels in 16-bit counter mode

4 channels in 8-bit counter mode

• 8-bit interval timer: 4 to 8 units

• Realtime clock: 1 channel (counting of one

second to 99 years, alarm interrupt, and clock

correction)

• Watchdog timer: 1 channel (operates with the low-

speed on-chip oscillator clock)

• External signal sampler: 1 channel

• Oscillation stop detector: 1 channel

LCD controller/driver

• Internal boosting, capacitive division, and external

resistor division are switchable as methods of

generating the driving voltage.

• Number of segment signal outputs: 19 to 56

• Number of common signal outputs: 4 to 8

A/D converter

• 8-/10-/12-bit resolution

• Analog input: 8 to 13 channels

• Internal reference voltage (1.48 V (typ.)) and

temperature sensor

D/A converter

• 8-bit resolution

• Analog output: 3 channels (one of the three

interfaces is only for the internal reference voltage

for the comparator)

• Output voltage: 0 V to VDD

• Realtime output function

Comparator

• 1 or 2 channels

• Operating modes: Comparator high-speed mode

and comparator low-speed mode

• The external reference voltage and the internal

reference voltage or D/A converter output are

selectable as the reference voltage.

Capacitive sensing unit

• Operating voltage condition: VDD = 1.8 to 5.5 V

• Self-capacitance method: A single pin configures

a single key, supporting up to 36 keys

• Mutual capacitance method: Matrix configuration

with 8 × 8 pins, supporting up to 64 keys

Input/output port pins

• Number of port pins: 40 to 95

N-ch open-drain I/O (withstand voltage of 6 V): 2

to 4,

N-ch open-drain I/O (VDD withstand voltage): 24

to 57,

Controlled current drive pins: 4 to 8

• Can be set to N-ch open drain or TTL input buffer,

and use of an on-chip pull-up resistor can be

specified.

• Connectable to a device with different voltage (1.8

V, 2.5 V, or 3 V)
