It delivers 50 ns min instruction execution at 20 MHz (2.7–5.5 V), integrates a 16×16-bit multiplier, 12-channel 10-bit ADC, dual comparators, real-time clock (Timer RH), and 72 programmable I/O ports - optimized for embedded control in LCD-based consumer appliances.
For engineers reviewing the R5F2LA88ADFP#V0 datasheet, R5F2LA88ADFP#V0 pinout, R5F2LA88ADFP#V0 application, or R5F2LA88ADFP#V0 equivalent, key selection criteria include its −40 to +85°C industrial temperature grade, 40-segment LCD drive capability, UART0/UART2 + I²C/SSU serial interfaces, low-power stop mode (0.5 µA), and on-chip debug support for rapid firmware iteration.
Technical Context
The R5F2LA88ADFP#V0 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit hardware multiplier for efficient signal processing. Its memory subsystem includes 64 KB program ROM, 2 KB × 2 data flash (10,000 write/erase cycles), and 3.5 KB RAM - enabling robust firmware updates and parameter storage without external EEPROM.
Peripheral integration includes Timer RJ0/RJ1/RJ2 (16-bit × 3) for precision timing and PWM generation, Timer RC (16-bit with 4 capture/compare registers), and a real-time clock (Timer RH) with calendar functionality. The device supports four clock sources: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - enabling flexible power/performance trade-offs across operating modes.
