Product details
Overview
R5F2LA88ANFP#YW from Renesas Electronics is an 80-pin LQFP (0.5 mm pitch) 16-bit R8C/LA8A Group MCU featuring a R8C CPU core, 64 KB program flash, 1 KB × 2 data flash, 3.5 KB RAM, 72 programmable I/O ports, and integrated LCD drive (40 segment outputs). It supports 10-bit × 12-channel A/D conversion, real-time clock (Timer RH), three 16-bit Timer RJ units, UART0/UART2 with I²C mode, and operates from 1.8 V to 5.5 V for household appliance control.
For engineers reviewing the R5F2LA88ANFP#YW datasheet, R5F2LA88ANFP#YW pinout, R5F2LA88ANFP#YW application, or R5F2LA88ANFP#YW equivalent, key selection criteria include its 80-pin LQFP-0.5mm package, N-grade (−20 to +85°C) temperature rating, on-chip data flash for parameter storage, and full peripheral set including dual UARTs, 12-channel ADC, and 40-segment LCD driver - critical for cost-sensitive, display-integrated embedded systems.
Technical Context
The R5F2LA88ANFP#YW implements the R8C CPU core with 89 fundamental instructions and hardware multiplier (16×16→32-bit), enabling efficient signal processing in resource-constrained applications. Its memory architecture includes 64 KB program ROM and dual 1 KB data flash blocks for field-updatable configuration storage.
Peripheral integration centers on system-level consolidation: Timer RJ0–RJ2 provide high-resolution timing and pulse measurement; UART2 supports I²C-bus communication; and the LCD drive circuit delivers static/1/2/1/3/1/4 duty driving with up to 40 segment outputs - all without external components.

What is the maximum operating frequency of the R5F2LA88ANFP#YW?
The R5F2LA88ANFP#YW supports up to 20 MHz operation when powered at 2.7–5.5 V using an external crystal on XIN/XOUT. At 1.8–5.5 V, the maximum frequency is 8 MHz. The internal high-speed oscillator can be adjusted for mid-range frequencies without external components, enabling flexible clocking for different power/performance trade-offs in the R5F2LA88ANFP#YW design.
Does the R5F2LA88ANFP#YW include on-chip debug capability?
Yes, the R5F2LA88ANFP#YW integrates a full on-chip debug function supporting breakpoints, single-stepping, and flash memory programming via the dedicated debug interface. This eliminates the need for external emulators during firmware development and allows in-system programming of both program ROM and data flash - essential for rapid iteration and field updates of the R5F2LA88ANFP#YW.
How many LCD segments can the R5F2LA88ANFP#YW drive directly?
The R5F2LA88ANFP#YW drives up to 40 segment outputs and 4 common outputs using its integrated LCD drive control circuit. It supports static, 1/2, 1/3, and 1/4 duty driving with 1/2 or 1/3 bias - sufficient for alphanumeric displays with icons in appliances. No external bias resistors or driver ICs are needed, reducing BOM cost and board space for the R5F2LA88ANFP#YW implementation.
What serial communication interfaces are available on the R5F2LA88ANFP#YW?
The R5F2LA88ANFP#YW provides UART0 (1 channel), UART2 (1 channel with selectable I²C-bus mode), and a shared Synchronous Serial Unit (SSU)/I²C interface. UART2's I²C capability allows direct connection to temperature sensors, EEPROMs, or display controllers without additional level-shifting or protocol translation - enhancing system integration for the R5F2LA88ANFP#YW.
Is there a drop-in replacement for the R5F2LA88ANFP#YW with higher memory capacity?
The R5F2LA8AANFP (96 KB program ROM) and R5F2LA8CANFP (128 KB program ROM) share identical pinout, peripherals, and package with the R5F2LA88ANFP#YW - enabling seamless migration for firmware growth. Both retain the same 3.5 KB RAM, 12-channel ADC, and 40-segment LCD driver, making them true memory-scaling alternatives without PCB redesign for the R5F2LA88ANFP#YW footprint.
