R5F103AAASP#10

This platform provides a true low-power solution for general-purpose applications, operating over a voltage range of 1.8V to 5.5V, featuring 2KB to 16KB of code flash, and delivering performance of up to 31 DMIPS at 24MHz.

Key features

• Ultra-low power technology; single supply voltage 1.8V to 5.5V; HALT, STOP, and SNOOZE modes.
• RL78 CPU core with CISC architecture and 3-stage pipeline; minimum instruction execution time scalable from high-speed (0.04167 μs at 24MHz high-speed on-chip oscillator) to ultra-low-speed (1 μs at 1MHz); 1 MB address space; general-purpose registers (8-bit register × 8) × 4 banks; on-chip RAM 256 B to 2 KB.
• Code flash memory 2 KB to 16 KB; block size 1 KB; block erase/rewrite prohibition (security function), on-chip debug, and self-programming (with flash protect window function).
• Data flash memory 2 KB; background operation supported — instructions executable from program memory during data flash rewrite; typical rewrite endurance 1,000,000 cycles; rewrite voltage VDD = 1.8V to 5.5V.
• High-speed on-chip oscillator selectable frequencies: 24 MHz, 16 MHz, 12 MHz, 8 MHz, 6 MHz, 4 MHz, 3 MHz, 2 MHz, and 1 MHz; high accuracy ±1.0% (VDD = 1.8V to 5.5V, TA = -20°C to +85°C).
• Operating ambient temperature: TA = -40°C to +85°C (A: consumer applications, D: industrial applications); TA = -40°C to +105°C (G: industrial applications).
• Power management and reset: on-chip power-on reset circuit and on-chip voltage detector (interrupt or reset selectable from 12 levels).
• DMA controller: 2 channels; 2-clock-cycle transfer between 8/16-bit SFRs and internal RAM.
• Multiplier/divider and multiply-accumulator: 16-bit × 16-bit = 32-bit (unsigned/signed), 32-bit × 32-bit = 32-bit (unsigned), and 16-bit × 16-bit + 32-bit = 32-bit (unsigned/signed).
• Serial interfaces: 1 to 3 channels simplified SPI, 1 to 3 channels UART, 0 to 3 channels simplified I2C, and 1 channel I2C.
• Timers: 4 to 8 channels 16-bit timer, 1 channel 12-bit interval timer, and 1 channel watchdog timer (operable with dedicated low-speed on-chip oscillator).
• A/D converter: 8/10-bit resolution; operating voltage VDD = 1.8V to 5.5V; 8 to 11 channels; internal reference voltage (1.45 V); temperature sensor.
• I/O ports: 18 to 26 pins (including 2 N-channel open-drain I/Os with 6V withstand voltage and 4 to 9 N-channel open-drain I/Os with VDD withstand voltage); configurable N-channel open-drain, TTL input buffer, and on-chip pull-up resistor; supports mixed-voltage interfacing with 1.8V/2.5V/3V devices; on-chip key interrupt; on-chip clock output/buzzer output controller.
• Other features: on-chip BCD correction circuit.
