The 1 KB RAM (1K x 8) handles the display buffer and control stack for segment LCD applications without external SRAM. The 64-LQFP package (12x12 mm) brings out 42 I/O pins, enough to drive a segment LCD panel, a keypad matrix, and a handful of sensor or actuator lines. On-chip peripherals include DMA for memory-to-LCD transfers, a PWM timer for backlight dimming, and a windowed watchdog timer (WDT) for safety-critical code paths. ## Supply flexibility and analog front-end The 1.6 V floor also supports two alkaline cells in series down to their end-of-life voltage. The 9-channel ADC (8- or 10-bit resolution) reads battery voltage, temperature sensors, or potentiometer inputs alongside the LCD drive. The ROHS3 compliance clears EU RoHS and China RoHS without exemption paperwork. ## Connectivity and peripheral mix for metering and HMI Serial interfaces include CSI (clocked serial interface, compatible with SPI), I²C for low-pin-count sensor buses, LINbus for automotive sub-networks, and UART/USART for debug or Modbus RTU links. The peripheral set — DMA, LCD controller, LVD, POR, PWM, WDT — is tailored for applications that wake from sleep, sample a sensor, update a display, then go back to standby. The on-chip LCD controller drives segment displays directly, eliminating a separate driver IC. Combined with the 4 KB EEPROM for calibration constants or last-state retention, the part suits gas/water meters, thermostats, and portable medical monitors where non-volatile storage must survive frequent write cycles.","metaTitle":"R5F10WLAAFA#10 Renesas RL78/L13 MCU, 24 MHz, 16 KB Flash","metaDescription":"R5F10WLAAFA#10 Renesas RL78/L13 16-bit MCU, 24 MHz, 16 KB flash, 4 KB EEPROM, 1 KB RAM, 42 I/O, industrial temp -40°C to 85°C.
