Product details
Overview
R5F2LA86ANFP#V0 from Renesas is an 80-pin LQFP R8C/LA8A Group 16-bit MCU with R8C CPU core, 32 KB program flash, 2 KB RAM, 12-channel 10-bit A/D converter, and integrated LCD drive (40 segment outputs). It supports 20 MHz operation at 2.7–5.5 V, features three 16-bit Timer RJ units, UART0/UART2 with I²C mode, and operates from −20°C to +85°C for appliance control applications.
For engineers reviewing the R5F2LA86ANFP#V0 datasheet, R5F2LA86ANFP#V0 pinout, R5F2LA86ANFP#V0 application, or R5F2LA86ANFP#V0 equivalent, key selection criteria include its 72 programmable I/O pins, high-current drive capability (10 pins), real-time clock (Timer RH), on-chip data flash (2 KB × 2), and low-power stop mode (0.5 µA).
Technical Context
The R5F2LA86ANFP#V0 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its system clock generation includes four independent circuits: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - enabling flexible power/performance trade-offs across wait, stop, and power-off modes.
Peripheral integration centers on mixed-signal timing and human interface support: Timer RJ0–RJ2 provide pulse width/period measurement and event counting; UART2 supports I²C-bus protocol; and the LCD drive circuit delivers static/1/2/1/3/1/4 duty with 1/2 or 1/3 bias for up to 40-segment displays - all sharing I/O pins with configurable pull-up resistors and interrupt-capable inputs.
