Product details
Overview
R5F2LA68ANFP#V0 from Renesas Electronics is a 16-bit R8C CPU core MCU in the R8C/LA6A Group, featuring 64 KB program flash, 1 KB × 2 data flash, and 3.5 KB RAM. It delivers 50 ns minimum instruction execution (at 20 MHz/2.7–5.5 V), integrates an on-chip 16×16→32-bit multiplier, and supports real-time clock (Timer RH), 10-bit × 8-channel A/D converter, and LCD drive control (up to 4 common / 32 segment pins) for embedded appliance control.
For engineers reviewing the R5F2LA68ANFP#V0 datasheet, R5F2LA68ANFP#V0 pinout, R5F2LA68ANFP#V0 application, or R5F2LA68ANFP#V0 equivalent, key selection criteria include its 64-pin LQFP (0.5 mm pitch) package, −20 to +85°C N-version operating range, integrated voltage detection with power-on reset, and support for wait/stop/power-off low-power modes with sub-µA current draw.
Technical Context
The R5F2LA68ANFP#V0 implements the R8C CPU core with 89 fundamental instructions and operates across a 1 Mbyte address space. Its system clock generation includes four independent circuits: XIN oscillator (20 MHz max), dedicated XCIN/XCOUT 32 kHz crystal input, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software-controlled clock switching.
Peripheral integration includes Timer RB (8-bit × 2), Timer RC (16-bit × 1 with 4 capture/compare registers), Timer RH (real-time clock with calendar mode), and Timer RJ (16-bit × 2). Serial interfaces comprise UART0, UART2 (with I²C-bus mode), and SSU (shared with I²C), while the A/D converter supports sweep mode, sample-and-hold, and on-die temperature sensing (−20 to +85°C).
