Overview
R5F2LA64ANFP#V0 from Renesas Electronics is a 16-bit R8C/LA6A Group microcontroller featuring the R8C CPU core, 16 KB program flash, 2 KB RAM, and 2 KB data flash. It delivers 50 ns minimum instruction execution at 20 MHz (VCC = 2.7–5.5 V), integrates an on-chip 16×16-bit multiplier, and supports real-time clock (Timer RH), 8-channel 10-bit A/D converter, and LCD drive control (max. 32 segment outputs). It targets embedded control in cost-sensitive, low-power consumer appliances with integrated display interfaces.
For engineers reviewing the R5F2LA64ANFP#V0 datasheet, R5F2LA64ANFP#V0 pinout, R5F2LA64ANFP#V0 application, or R5F2LA64ANFP#V0 equivalent, key selection criteria include its 64-pin LQFP (0.5 mm pitch) package, N-grade temperature range (−20 to +85°C), programmable I/O count (56 pins), and integrated peripherals including UART0, SSU/I²C, Timer RB/RC/RH/RJ, and voltage detection circuitry.
Technical Context
The R5F2LA64ANFP#V0 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit hardware multiplier for efficient arithmetic-intensive tasks. Its memory subsystem includes 16 KB of program flash with 10,000-cycle endurance, 2 KB of RAM, and 2 KB of data flash supporting in-system rewriting and ROM code protection.
Peripheral integration centers on mixed-signal control: an 8-channel 10-bit A/D converter with sample-and-hold and internal temperature sensor (−20 to +85°C), LCD drive circuit supporting static/1/2/1/3/1/4 duty and 1/2 or 1/3 bias, and three independent 16-bit timer units (Timer RJ ×2, Timer RC ×1) plus 8-bit Timer RB ×2 for PWM, capture/compare, and real-time clock functions.
