Overview
R5F2LA86ANFP#30 from Renesas Electronics is a 16-bit R8C/LA8A Group microcontroller featuring the R8C CPU core, 32 KB program flash, 2 KB RAM, and 2 KB data flash. It delivers 50 ns minimum instruction execution at 20 MHz (VCC = 2.7–5.5 V), integrates a 16×16-bit hardware multiplier, and supports 72 programmable CMOS I/O pins with 10 high-current drive outputs. It is used in LCD-based consumer appliances requiring integrated timing, analog sensing, and low-power operation.
For engineers reviewing the R5F2LA86ANFP#30 datasheet, R5F2LA86ANFP#30 pinout, R5F2LA86ANFP#30 application, or R5F2LA86ANFP#30 equivalent, key selection considerations include its 12-channel 10-bit ADC with temperature sensor, 40-segment LCD driver, Timer RJ0–RJ2 triple 16-bit timers, UART0/UART2 dual serial interfaces, and support for wait/stop/power-off low-power modes down to 0.01 µA.
Technical Context
The R5F2LA86ANFP#30 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its memory subsystem includes on-chip 32 KB flash (program), 2 KB SRAM, and 2 KB data flash with 10,000-cycle endurance and ROM code protection.
Peripheral integration centers on real-time control: Timer RH provides calendar-mode RTC functionality; Timer RJ0–RJ2 enable precision pulse generation, event counting, and PWM; 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.

The device maintains full peripheral functionality across this entire voltage range.
Does the R5F2LA86ANFP#30 include an integrated temperature sensor, and what is its accuracy range?
Yes, the R5F2LA86ANFP#30 includes an on-chip temperature sensor usable with the 10-bit ADC. It is specified for −20 to +85°C (N version), matching the device's operating ambient temperature range. Calibration data is not factory-trimmed; users must perform two-point calibration in-system for ±2°C typical accuracy across the range.
How many LCD segments can the R5F2LA86ANFP#30 drive, and what bias/duty configurations are supported?
The R5F2LA86ANFP#30 drives up to 40 segment outputs and 4 common outputs. It supports static, 1/2, 1/3, and 1/4 duty cycles with 1/2 or 1/3 bias - compatible with most passive segment LCDs used in consumer appliance displays. Segment assignment is fully configurable via P0–P4 port registers and LSE5 control bits.
What debug and programming interfaces does the R5F2LA86ANFP#30 support?
The R5F2LA86ANFP#30 supports Renesas' on-chip debugging interface via dedicated pins (RESET, TXD0, RXD0) using standard FINE protocol. It enables full-speed real-time trace, flash programming, and breakpoint debugging without external JTAG emulators. No external debug hardware is required beyond a USB-to-serial adapter and Renesas CS+ or e² studio IDE.
Is the R5F2LA86ANFP#30 pin-compatible with other R8C/LA8A Group MCUs like R5F2LA84ANFP#30 or R5F2LA88ANFP#30?
Yes, all R8C/LA8A Group devices in the PLQP0080KB-A package - including R5F2LA84ANFP#30 (16 KB), R5F2LA86ANFP#30 (32 KB), R5F2LA88ANFP#30 (64 KB), and R5F2LA8AANFP#30 (96 KB) - share identical pinouts, peripheral mappings, and electrical characteristics. Firmware and PCB designs are interchangeable across these variants, differing only in flash/RAM capacity.
