Overview
R5F2LA87ANFA#V0 from Renesas is an 8-bit R8C/LA8A Group MCU featuring the R8C CPU core, 48 KB program flash, 3.5 KB RAM, and integrated data flash. It delivers 50 ns minimum instruction execution at 20 MHz (2.7–5.5 V), supports 72 programmable I/O ports including 10 high-current drive pins, and integrates 12-channel 10-bit ADC, dual comparators, real-time clock (Timer RH), and LCD segment driver (40 segments). It targets cost-sensitive, low-power consumer appliance control with on-chip debug and flash rewrite capability.
For engineers reviewing the R5F2LA87ANFA#V0 datasheet, R5F2LA87ANFA#V0 pinout, R5F2LA87ANFA#V0 application, or R5F2LA87ANFA#V0 equivalent, key selection criteria include its 80-pin LQFP-0.65 mm package, −20 to +85°C N-version temperature grade, 12-channel ADC with temperature sensor, Timer RJ×3 for precision timing, and UART0/UART2 + I²C/SSU serial interfaces for system connectivity.
Technical Context
The R5F2LA87ANFA#V0 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient arithmetic. Its memory subsystem includes 48 KB program ROM, 1 KB × 2 data flash, and 3.5 KB RAM - all accessible within a 1 Mbyte address space in single-chip mode.
Peripheral integration centers on mixed-signal control: Timer RJ×3 provides three independent 16-bit channels for PWM, event counting, and pulse measurement; UART2 supports I²C-bus mode and multiprocessor communication; 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.

What is the maximum operating frequency and supply voltage range for the R5F2LA87ANFA#V0?
The R5F2LA87ANFA#V0 operates at up to 20 MHz with a supply voltage of 2.7–5.5 V, or at 8 MHz down to 1.8 V. Its minimum instruction execution time is 50 ns under 20 MHz/2.7–5.5 V conditions and 125 ns under 8 MHz/1.8–5.5 V conditions - enabling flexible power/performance trade-offs in battery- or line-powered appliances.
Does the R5F2LA87ANFA#V0 support in-system programming and debug?
Yes, the R5F2LA87ANFA#V0 includes full on-chip debug functionality and on-board flash rewrite capability. It supports programming and erasure of both program ROM and data flash under normal VCC (1.8–5.5 V), with 10,000-cycle endurance for both memory types - enabling field firmware updates and production-line calibration without external programmers.
How many analog input channels does the R5F2LA87ANFA#V0 ADC support, and what is its resolution?
The R5F2LA87ANFA#V0 integrates a 10-bit resolution successive-approximation ADC with 12 input channels, including sample-and-hold and sweep mode. It also incorporates an on-die temperature sensor covering −20 to +85°C (N version), allowing direct thermal monitoring without external sensors in applications like refrigerator evaporator control or microwave cavity safety cutoff.
What LCD display configurations are supported by the R5F2LA87ANFA#V0?
The R5F2LA87ANFA#V0 LCD drive control circuit supports up to 40 segment outputs and 4 common outputs, with selectable duty (static, 1/2, 1/3, 1/4) and bias (1/2 or 1/3). This enables direct drive of 4-digit × 16-segment displays or 3-line × 12-character alphanumeric modules - eliminating external LCD drivers in cost-sensitive consumer HMI designs.
Is the R5F2LA87ANFA#V0 pin-compatible with other R8C/LA8A Group MCUs?
Yes, all R8C/LA8A Group MCUs in the same package variant - including R5F2LA84ANFA, R5F2LA86ANFA, R5F2LA87ANFA#V0, and R5F2LA88ANFA - share identical 80-pin LQFP-0.65 mm (PLQP0080JA-A) pinouts and peripheral mappings. Firmware and hardware designs are interchangeable across these variants, differing only in program ROM size and part number suffix.
