Renesas R5F2LA8AANFP#V0

Overview

R5F2LA8AANFP#V0 from Renesas is a 16-bit R8C/LA8A Group microcontroller featuring the R8C CPU core, 96 KB program flash, 4 KB data flash (2 × 2 KB), and 5.5 KB RAM. It delivers 50 ns minimum instruction execution at 20 MHz (V_CC = 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 units, and 12-channel 10-bit A/D conversion - deployed in appliance control panels requiring integrated LCD drive and low-power operation.

For engineers reviewing the R5F2LA8AANFP#V0 datasheet, R5F2LA8AANFP#V0 pinout, R5F2LA8AANFP#V0 application, or R5F2LA8AANFP#V0 equivalent, key selection criteria include its 80-pin LQFP package with 72 programmable I/Os, 40-segment LCD driver, dual comparator B circuits, and support for voltage detection, wait/stop/power-off low-power modes, and on-chip debug.

Technical Context

The R5F2LA8AANFP#V0 implements the R8C CPU core with 89 fundamental instructions and operates across a 1 Mbyte address space. Its system clock generation includes four independent circuits: XIN oscillator (up to 20 MHz), dedicated XCIN/XCOUT 32 kHz crystal input, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - enabling flexible clock source selection and oscillation stop detection.

Peripheral integration includes Timer RB (8-bit × 2), Timer RC (16-bit × 1 with 4 capture/compare registers), Timer RH (real-time clock with calendar function), and Timer RJ0–RJ2 (16-bit × 3 with pulse width/period measurement, event counting, and PWM output). Serial interfaces comprise UART0, UART2 (with I²C mode), and SSU (shared with I²C-bus).

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R5F2LA8AANFP#V0?

The R5F2LA8AANFP#V0 supports up to 20 MHz operation at V_CC = 2.7–5.5 V, and 8 MHz operation down to V_CC = 1.8 V. This dual-frequency capability allows design flexibility across battery-powered and line-powered appliances while maintaining deterministic timing at both extremes.

Does the R5F2LA8AANFP#V0 include an on-chip temperature sensor, and what is its accuracy range?

Yes, the R5F2LA8AANFP#V0 integrates an on-chip temperature sensor with a measurement range of −20 to 85 °C for the N version. It is factory-calibrated and usable for ambient temperature monitoring, thermal derating, or self-test routines without external components.

How many LCD segments and commons does the R5F2LA8AANFP#V0 support, and what bias/duty configurations are available?

The R5F2LA8AANFP#V0 supports up to 40 segment outputs and 4 common outputs. It provides selectable LCD bias (1/2, 1/3) and duty (static, 1/2, 1/3, 1/4) modes - enabling direct drive of alphanumeric displays up to 4-digit × 7-segment + decimal points or custom segment layouts.

What low-power modes are implemented in the R5F2LA8AANFP#V0, and what is the lowest current consumption achievable?

The R5F2LA8AANFP#V0 offers Wait, Stop, Power-Off 0, and Power-Off 2 modes. The lowest active current is 0.01 µA in Power-Off 0 mode (Timer RH disabled), and 1.3 µA in Power-Off 2 mode (Timer RH enabled), both measured at V_CC = 3.0 V - ideal for battery-backed real-time clock applications.

Is the R5F2LA8AANFP#V0 pin-compatible with other members of the R8C/LA8A Group, such as R5F2LA86ANFP or R5F2LA8CANFP?

Yes, all R8C/LA8A Group devices in the PLQP0080KB-A package - including R5F2LA8AANFP#V0, R5F2LA86ANFP, and R5F2LA8CANFP - share identical 80-pin LQFP pinouts and electrical characteristics. Firmware and hardware designs are interchangeable across this group, differing only in flash/RAM capacity and part marking.
