Product details
Overview
R5F2L3A8ANFP#U1 from Renesas Electronics is an 8-bit R8C/L3AA Group microcontroller featuring 64 KB flash program ROM, 1 KB × 4 data flash with background operation (BGO), 8 KB RAM, and integrated LCD controller supporting up to 8 common and 56 segment outputs. It operates at up to 20 MHz (VCC = 2.7–5.5 V), delivers 88 programmable CMOS I/O pins with 16 high-current drive ports, and targets embedded control in appliance front panels and industrial HMI displays.
For engineers reviewing the R5F2L3A8ANFP#U1 datasheet, R5F2L3A8ANFP#U1 pinout, R5F2L3A8ANFP#U1 application, or R5F2L3A8ANFP#U1 equivalent, key selection criteria include its 100-pin LQFP package, -20°C to +85°C operating temperature (N version), integrated real-time clock (timer RE), LIN-capable UART0, and 20-channel 10-bit ADC - all confirmed for this exact part number in Renesas' preliminary specification REJ03B0243-0030.
Technical Context
The R5F2L3A8ANFP#U1 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. Its memory architecture includes on-chip flash with BGO support, enabling firmware updates without halting execution.
It integrates dual clock systems: a 20 MHz external XIN oscillator and a 32 kHz XCIN crystal circuit, plus high- and low-speed on-chip oscillators. Power management includes wait, stop, and power-off modes with sub-µA current draw - e.g., 1 µA in power-off mode with timer RE active.
Key Specifications
