This device integrates an LCD controller/driver, built on a true ultra-low-power platform (operating current as low as 71 μA/MHz, RTC plus low-voltage detector at 0.61 μA), with an operating voltage range of 1.6 V to 5.5 V, 16 KB to 128 KB flash memory, and performance of 31 DMIPS at 24 MHz — suitable for all LCD-based applications.

Key features

• Ultra-low power consumption technology: single supply voltage VDD of 1.6 V to 5.5 V, supporting 1.8 V device operation at low voltage; supports HALT mode, STOP mode, and SNOOZE mode.
• RL78 CPU core: CISC architecture with 3-stage pipeline; minimum instruction execution time switchable from high-speed (0.04167 µs, based on 24 MHz high-speed on-chip oscillator) to ultra-low-speed (30.5 µs, based on 32.768 kHz subsystem clock); 1 MB address space; general-purpose registers of (8-bit registers × 8) × 4 banks; on-chip RAM of 1 KB to 8 KB.
• Code flash memory: 16 KB to 128 KB capacity; 1 KB block size; supports block erase and rewrite prohibition (security function); on-chip debug capability; supports self-programming (with boot swap function / flash protection window function).
• Data flash memory: 4 KB capacity; supports background operation, allowing instruction execution from program memory during data flash rewrite; typical endurance of 1,000,000 erase/write cycles; rewrite voltage VDD of 1.8 V to 5.5 V.
• High-speed on-chip oscillator: selectable frequencies of 48 MHz, 24 MHz, 16 MHz, 12 MHz, 8 MHz, 6 MHz, 4 MHz, 3 MHz, 2 MHz, and 1 MHz; high accuracy of ±1.0% (conditions: VDD = 1.8 V to 5.5 V, TA = -20°C to +85°C).
• Operating ambient temperature: TA = -40°C to +85°C (A: consumer applications); TA = -40°C to +105°C (G: industrial applications).
• Power management and reset functions: on-chip power-on reset circuit; on-chip voltage detector (selectable interrupt and reset from 14 levels).
• DMA controller: 4 channels; 2 clock cycles for transfers between 8/16-bit special function registers and internal RAM.
• Multiplier/divider and multiply-accumulator: supports 16-bit × 16-bit = 32-bit (unsigned or signed); 32-bit ÷ 32-bit = 32-bit (unsigned); 16-bit × 16-bit + 32-bit = 32-bit (unsigned or signed).
• Serial interfaces: 2-channel simplified SPI; 3 or 4-channel UART/UART (with LIN bus support) / 1 channel; 1-channel I2C / 2-channel simplified I2C communication.
• Timers: 8-channel 16-bit timer (with remote control output function); 1-channel 16-bit timer KB20 (high-side PWM output function only); 1-channel 12-bit interval timer; 1-channel real-time clock 2 (supports 99-year calendar, alarm function, and clock correction function); 1-channel watchdog timer (operable with dedicated low-speed on-chip oscillator).
• A/D converter: 8/10-bit resolution A/D converter (VDD = 1.6 V to 5.5 V); 9 to 12 analog input channels; selectable internal reference voltage (1.45 V) and temperature sensor.
• Comparator: 2 channels; selectable operating modes: comparator high-speed mode, comparator low-speed mode, or window mode; selectable external or internal reference voltage.
• LCD controller/driver: segment signal outputs of 36 (32 with 8 commons) to 51 (47 with 8 commons); common signal outputs of 4 (8); switchable between internal voltage boost method, capacitive voltage division method, and external resistive voltage division method.
• I/O ports: 49 to 65 I/O ports (including 2 N-channel open-drain I/Os with 6 V withstand voltage, and 12 to 18 N-channel open-drain I/Os with VDD withstand voltage); configurable as N-channel open-drain, TTL input buffer, and on-chip pull-up resistor; supports multi-voltage interfacing for 1.8 V/2.5 V/3 V devices; on-chip key interrupt function; on-chip clock output/buzzer output controller.
• Other: on-chip BCD correction circuit.
