1. OUTLINE
1.1 Features
Ultra-low power consumption technology • VDD = single power supply voltage of 1.6 to 3.6 V • 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 μs: @ 24 MHz operation with high-speed on-chip oscillator clock or PLL clock) to ultra-low speed (30.5 μs: @ 32.768 kHz operation with subsystem clock) • Multiply/divide and multiply/accumulate instructions are supported. • Address space: 1 Mbyte • General-purpose registers: (8-bit register × 8) × 4 banks • On-chip RAM: 8 to 16 KB
Code flash memory • Code flash memory: 64 to 256 KB • Block size: 1 KB • Prohibition of block erase and rewriting (security function) • On-chip debug function • Self-programming (with boot swap function/flash shield window
function)
Data flash memory • Data flash memory: 8 KB • Background operation (BGO): Instructions can be 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 3.6 V
High-speed on-chip oscillator • Select from 48 MHz, 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 3.6 V, TA = -20 to +85°C)
Operating ambient temperature • TA = -40 to +85°C (A: Consumer applications) • TA = -40 to +105°C (G: Industrial applications)
Power management and reset function • On-chip power-on-reset (POR) circuit • On-chip voltage detector (LVD) (Select interrupt and reset from 12
levels)
Data transfer controller (DTC) • Transfer modes: Normal transfer mode, repeat transfer mode, block
transfer mode • Activation sources: Activated by interrupt sources (30 to 33 sources). • Chain transfer function
Event link controller (ELC) • Event signals of 30 or 31 types can be linked to the specified
peripheral function.
Serial interfaces • CSI: 4 channels • UART/UART (LIN-bus supported): 4 channels • I2C/simplified I2C: 5 channels
Timers • 16-bit timer: 11 channels • 12-bit interval timer: 1 channel • Real-time clock 2: 1 channel (calendar for 99 years, alarm function,
and clock correction function) • Watchdog timer: 1 channel (operable with the dedicated low-speed
on-chip oscillator)
LCD controller/driver • Internal voltage boosting method, capacitor split method, and
external resistance division method are switchable. • Segment signal output: 44 (40) Note 1 to 56 (52) Note 1 • Common signal output: 4 (8) Note 1
USB Note 2 • USB version 2.0 (function controller) • Full-speed transfer (12 Mbps) and low-speed transfer (1.5 Mbps) are
supported • Compliant to Battery Charging Specification Revision 1.2
A/D converter • 8/10-bit resolution A/D converter (VDD = 1.6 to 3.6 V) • 12-bit resolution A/D converter (VDD = 2.4 to 3.6 V) • Analog input: 9 to 13 channels • Internal reference voltage (TYP. 1.45 V) and temperature sensor Note 2
D/A converter • 8-bit resolution D/A converter (VDD = 1.6 to 3.6 V) • Analog output: 2 channels • Output voltage: 0 V to VDD • Real-time output function
Comparator • 2 channels • Operating modes: Comparator high-speed mode, comparator low-
speed mode, window mode • The external reference voltage or internal reference voltage can be
selected as the reference voltage.
I/O ports • I/O ports: 59 to 77 (N-ch open drain I/O [withstand voltage of 6 V]: 2) • Can be set to N-ch open drain, TTL input buffer, and on-chip pull-up
resistor • On-chip key interrupt function • On-chip clock output/buzzer output controller
Others • On-chip BCD (binary-coded decimal) correction circuit
Note 1. Note 2.
The number in parentheses indicates the number of signal outputs when 8 coms are used. Selectable only in HS (high-speed main) mode.
Remark The functions mounted depend on the product. See 1.6 Outline of Functions.
