True low-power platform (66 μA/MHz, and 0.60 μA for operation with only RTC and LVD) for the general-purpose applications, with 1.6-V to 5.5-V operation, 16- to 512-Kbyte code flash memory, and 44 DMIPS at 32 MHz
1. OUTLINE
1.1 Features
Ultra-Low Power Consumption Technology • VDD = single power supply voltage of 1.6 to 5.5 V which
can operate a 1.8 V device 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 (0.03125 s: @ 32 MHz operation with high-speed on-chip oscillator) to ultra-low speed (30.5 s: @ 32.768 kHz operation with subsystem clock) • Multiply/divide/multiply & accumulate instructions are supported. • Address space: 1 MB • General-purpose registers: (8-bit register 8) 4 banks • On-chip RAM: 2.5 to 48 KB
Code Flash Memory • Code flash memory: 16 to 512 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: 4 KB and 8 KB • Back ground 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 5.5 V
High-speed On-chip Oscillator • Select from 64 MHz, 48 MHz, 32 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 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)
Power Management and Reset Function • On-chip power-on-reset (POR) circuit • On-chip voltage detector (LVD) (Select interrupt and
reset from 14 levels)
Data Transfer Controller (DTC) • Transfer modes: Normal transfer mode, repeat transfer
mode, block transfer mode • Activation sources: Activated by interrupt sources. • Chain transfer function
Event Link Controller (ELC) • Event signals of 19 to 26 types can be linked to the
specified peripheral function.
Serial Interfaces • CSI: 3 to 8 channels • UART/UART (LIN-bus supported): 3 or 4 channels • I2C/simplified I2C: 3 to 8 channels
Timer • 16-bit timer: 8 to 12 channels
(Timer Array Unit (TAU): 4 to 8 channels, Timer RJ: 1 channel, Timer RD: 2 channels, Timer RG: 1 channel) • 12-bit interval timer: 1 channel • Real-time clock: 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)
A/D Converter • 8/10-bit resolution A/D converter (VDD = 1.6 to 5.5 V) • Analog input: 8 to 20 channels • Internal reference voltage (1.45 V) and temperature
sensor
D/A Converter • 8-bit resolution D/A converter (VDD = 1.6 to 5.5 V) • Analog output: None or up to two channels • Output voltage: 0 V to VDD • Real-time output function
Comparator • None or up to two 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 Port • I/O port: 26 to 92 (N-ch open drain I/O [withstand
voltage of 6 V]: 2 to 4, N-ch open drain I/O [VDD withstand voltage/EVDD withstand voltage]: 10 to 28) • Can be set to N-ch open drain, TTL input buffer, and onchip 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
Remark The functions mounted depend on the product.
