Product details
Overview
R5F2LA8AADFP#30 from Renesas Electronics is a 16-bit R8C/LA8A Group microcontroller featuring the R8C CPU core, 96 KB program flash, 2 KB × 2 data flash, and 5.5 KB RAM. It delivers 50 ns minimum instruction execution at 20 MHz (VCC = 2.7–5.5 V), integrates a 16×16→32-bit hardware multiplier, and supports real-time clock (Timer RH), three 16-bit Timer RJ channels, and 12-channel 10-bit A/D conversion - deployed in appliance control panels with integrated LCD display.
For engineers reviewing the R5F2LA8AADFP#30 datasheet, R5F2LA8AADFP#30 pinout, R5F2LA8AADFP#30 application, or R5F2LA8AADFP#30 equivalent, key selection criteria include its 80-pin LQFP package, −40 to +85°C industrial temperature grade (D version), 40-segment LCD drive capability, UART0/UART2 dual serial interfaces with I²C mode, and high-current I/O (10 pins) for direct LED/relay driving without external buffers.
Technical Context
The R5F2LA8AADFP#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, dual-bank data flash (1 KB × 2) enabling background rewrite, and RAM with selectable wait states.
Peripheral integration centers on mixed-signal timing and human interface: Timer RH provides calendar-based RTC with alarm output; Timer RJ0–RJ2 support pulse width measurement, event counting, and programmable waveform generation; and the LCD controller drives up to 40 segments with static/1/2/1/3/1/4 duty and 1/2 or 1/3 bias - all operating concurrently with low-power modes including stop mode (0.5 µA).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2LA88ADFP | 64 KB program flash, same 80-pin LQFP package, identical peripherals and pinout - differs only in ROM size and data flash configuration (1 KB × 2 vs. 2 KB × 2). | Suitable where firmware footprint < 64 KB and reduced data logging depth is acceptable - e.g., basic timer-based appliances without OTA update needs. | Select R5F2LA88ADFP when code size permits and lower data flash endurance requirements apply; no PCB or firmware changes needed. |
| R5F2LA8AANFP | Same 96 KB flash and 2 KB × 2 data flash, but N-version (−20 to +85°C) instead of D-version; otherwise identical electrical and functional specification. | Applicable in commercial-grade indoor equipment (e.g., office printers, audio receivers) where extended industrial temperature range is unnecessary. | Choose R5F2LA8AANFP for cost-sensitive consumer applications operating within 0–70°C ambient - avoids D-version premium without sacrificing functionality. |
