Product details
Overview
R5F2LA88ANFA#U0 from Renesas is an 80-pin LQFP (0.65 mm pitch) 16-bit R8C/LA8A Group MCU featuring 64 KB flash, 3.5 KB RAM, 12-channel 10-bit ADC, 72 programmable I/O ports, and integrated LCD drive (40 segment/4 common) for embedded control in consumer appliances and industrial HMI. It operates from 1.8–5.5 V with ultra-low power stop mode (0.01 µA) and supports real-time clock, UART/I²C/SSU serial interfaces, and three 16-bit Timer RJ channels.
For engineers reviewing the R5F2LA88ANFA#U0 datasheet, R5F2LA88ANFA#U0 pinout, R5F2LA88ANFA#U0 application, or R5F2LA88ANFA#U0 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, N-grade (−20 to +85°C) temperature rating, on-chip data flash (2 × 1 KB), high-current drive capability (10 pins), and full R8C CPU core compatibility with multiplier and 1 Mbyte address space.
Technical Context
The R5F2LA88ANFA#U0 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit hardware multiplier, enabling efficient signal processing and control loop execution. Its memory architecture includes program ROM, data flash (1 KB × 2), and RAM - all accessible within a unified 1 Mbyte address space.
It integrates four independent clock sources (XIN, XCIN, high-speed/low-speed on-chip oscillators), configurable low-power modes (wait, stop, power-off), and peripheral subsystems including Timer RH (real-time clock), Timer RJ0–RJ2 (16-bit × 3), and dual comparator B circuits - all mapped to shared I/O pins with flexible function selection via register configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2LA88ANFP | Same die, 80-pin LQFP with 0.5 mm pitch (PLQP0080KB-A) instead of 0.65 mm (PLQP0080JA-A) | Requires PCB redesign due to finer pitch; identical electrical specs and firmware compatibility | Select when higher pin density and smaller footprint are prioritized over assembly ease |
| R5F2LA86ANFA | Same package and temperature grade, but reduced program ROM (32 KB vs. 64 KB) and same 3.5 KB RAM | Suitable for simpler firmware with smaller code footprint; retains all peripherals including LCD, ADC, and timers | Choose for cost-sensitive designs where application code fits in 32 KB and future firmware growth is limited |
Compared with R5F2LA88ANFP, the R5F2LA88ANFA#U0 offers easier hand-soldering and rework due to its 0.65 mm pitch, while versus R5F2LA86ANFA it delivers double the program flash for complex UI logic or protocol stacks - both alternatives retain identical peripheral sets and pin-compatible I/O mapping.

FAQ
What is the maximum operating frequency of the R5F2LA88ANFA#U0?
The R5F2LA88ANFA#U0 supports a maximum external crystal frequency of 20 MHz at VCC ≥ 2.7 V, delivering a minimum instruction execution time of 50 ns. At lower supply voltages (1.8–2.6 V), the maximum supported XIN frequency is 8 MHz with 125 ns minimum instruction time - ensuring reliable operation across wide voltage ranges.
Does the R5F2LA88ANFA#U0 include an on-chip temperature sensor?
Yes, the R5F2LA88ANFA#U0 includes an integrated temperature sensor with a specified measurement range of −20 to +85°C for the N-version device. The sensor output is routed to the ADC input channel AN6 and requires calibration per the datasheet's offset/gain correction procedure to achieve ±3°C accuracy.
Can the R5F2LA88ANFA#U0 drive a 40-segment LCD without external components?
Yes, the R5F2LA88ANFA#U0's built-in LCD drive control circuit supports up to 40 segment outputs and 4 common outputs with selectable bias (1/2, 1/3) and duty (static, 1/2, 1/3, 1/4). When configured with external VL1–VL3 resistors and COM pins, it drives standard static or multiplexed LCD glass directly - no external driver IC or charge pump required.
What debug and programming interfaces does the R5F2LA88ANFA#U0 support?
The R5F2LA88ANFA#U0 supports on-chip debugging via the single-wire background debug mode (BDM) using the dedicated BKGD pin (P8_0), compatible with Renesas E1/E20 emulators. Flash programming is performed through the same interface, enabling full read/write/erase operations and security lock/unlock without requiring additional programming hardware.
Is the R5F2LA88ANFA#U0 pin-compatible with other R8C/LA8A Group MCUs?
Yes, all R8C/LA8A Group devices in the same package variant (e.g., PLQP0080JA-A) share identical pinouts, including R5F2LA84ANFA, R5F2LA86ANFA, R5F2LA88ANFA#U0, and R5F2LA8AANFA. Firmware and hardware designs are interchangeable across these variants - only flash size, RAM capacity, and optional features (e.g., UART2 presence) differ.
