It delivers 50 ns minimum instruction execution (at 20 MHz/5.5 V), integrates a 16×16→32-bit hardware multiplier, and supports 56 programmable CMOS I/O pins with 8 high-current drive ports - optimized for embedded control in LCD-based consumer appliances.
For engineers reviewing the R5F2LA68ANFP#30 datasheet, R5F2LA68ANFP#30 pinout, R5F2LA68ANFP#30 application, or R5F2LA68ANFP#30 equivalent, key selection criteria include its 64-pin LQFP (0.5 mm pitch) package, integrated LCD segment driver (up to 32 segments), 8-channel 10-bit A/D converter with temperature sensor, and dual UART/I²C-capable serial interfaces for appliance HMI and sensor subsystems.
Technical Context
The R5F2LA68ANFP#30 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16-bit multiplier supporting multiply-accumulate operations. Its memory subsystem includes on-chip program ROM, data flash with 10,000 erase/write cycles, and RAM with built-in retention in low-power modes.
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 functions), and Timer RJ (16-bit ×2 for PWM, event counting, and pulse measurement). It supports three clock sources: XIN (up to 20 MHz), XCIN (32 kHz), and on-chip oscillators (high- and low-speed).
