Overview
R5F2LA64ADFP#30 from Renesas Electronics is a 16-bit R8C/LA6A Group microcontroller with 16 KB flash program ROM, 2 KB RAM, and 2 KB data flash. It features a 56-pin LQFP package (PLQP0064KB-A), −40 to +85°C industrial temperature grade (D version), 10-bit A/D converter across 8 channels, and integrated LCD drive control supporting up to 32 segment outputs. It targets embedded control in appliance user interfaces requiring low-power operation and on-chip display management.
For engineers reviewing the R5F2LA64ADFP#30 datasheet, R5F2LA64ADFP#30 pinout, R5F2LA64ADFP#30 application, or R5F2LA64ADFP#30 equivalent, key selection criteria include its 56 I/O ports (8 high-current), Timer RJ ×2 (16-bit), UART0 + SSU/I²C serial interface, real-time clock (Timer RH), and support for wait/stop/power-off low-power modes down to 0.01 µA.
Technical Context
The R5F2LA64ADFP#30 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and 1 Mbyte address space. It supports four clock sources: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software-controlled frequency divider (1/2/4/8/16).
Peripheral integration includes Timer RB0/RB1 (8-bit ×2), Timer RC (16-bit with 4 capture/compare registers), Timer RH (real-time clock with calendar function), and Timer RJ0/RJ1 (16-bit ×2 with pulse width/period measurement). The device also embeds voltage detection (power-on reset + VDD monitor), watchdog timer (14-bit with prescaler), and temperature sensor (−40 to +85°C range).
