Product details
Overview
R5F2LA8AANFP#30 from Renesas Electronics 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 (VCC = 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 channels, and 12-channel 10-bit A/D conversion - deployed in household appliance control panels with integrated LCD displays.
For engineers reviewing the R5F2LA8AANFP#30 datasheet, R5F2LA8AANFP#30 pinout, R5F2LA8AANFP#30 application, or R5F2LA8AANFP#30 equivalent, key selection criteria include its 80-pin LQFP package, 72 programmable I/O ports (including 10 high-current drive pins), 40-segment LCD driver capability, dual UART/I²C/SSU serial interfaces, and −20 to +85°C industrial temperature grade (N version).
Technical Context
The R5F2LA8AANFP#30 implements the R8C CPU core with 89 fundamental instructions and single-chip 1 Mbyte address space. Its system clock generation includes four independent circuits: XIN oscillator (up to 20 MHz), dedicated 32 kHz XCIN/XCOUT crystal input, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - enabling flexible power-mode sequencing across wait, stop, and multiple power-off states.
Peripheral integration centers on deterministic timing and mixed-signal control: Timer RJ0–RJ2 provide 16-bit event counting, pulse width/period measurement, and programmable waveform generation; Timer RC offers 4 capture/compare registers for PWM output on 3 pins; and the 12-channel A/D converter includes sample-and-hold, sweep mode, and an on-die temperature sensor calibrated for −20 to +85°C operation.

FAQ
What is the operating temperature range for the R5F2LA8AANFP#30?
The R5F2LA8AANFP#30 is an N-version device rated for −20°C to +85°C ambient operating temperature. This specification applies to all core functions including the 12-channel A/D converter, 40-segment LCD driver, and real-time clock (Timer RH). The on-die temperature sensor is calibrated across this full range, enabling accurate thermal compensation in appliance control applications.
Does the R5F2LA8AANFP#30 support in-system programming of its data flash?
Yes, the R5F2LA8AANFP#30 supports in-application programming (IAP) of its 4 KB data flash (organized as two 2 KB blocks) using standard VCC supply (1.8–5.5 V). Each block endures 10,000 erase/write cycles and includes hardware security features like ROM code protect and ID code check to prevent unauthorized access during field updates.
How many external interrupt sources does the R5F2LA8AANFP#30 provide?
The R5F2LA8AANFP#30 provides 8 dedicated external interrupt pins (INT0–INT7) plus 8 key input (KI0–KI7) lines that can be configured as additional edge-triggered interrupts. All 16 sources are individually maskable and support 7 priority levels, enabling responsive handling of button presses, sensor alerts, and communication events in real-time appliance control.
Can the R5F2LA8AANFP#30 drive a 4×20 character LCD directly?
Yes, the R5F2LA8AANFP#30's integrated LCD drive control circuit supports up to 40 segment outputs and 4 common outputs - sufficient to drive a standard 4×20 character LCD (80 segments + 4 commons). It supports 1/2 and 1/3 bias configurations and static/1/2/1/3/1/4 duty cycles, eliminating need for external LCD driver ICs in cost-sensitive appliance designs.
What clock sources are available for the real-time clock (Timer RH) in the R5F2LA8AANFP#30?
The Timer RH real-time clock in the R5F2LA8AANFP#30 is driven exclusively by the dedicated 32 kHz XCIN/XCOUT crystal oscillator circuit. This low-frequency source operates independently of the main XIN clock and remains active in stop and power-off modes (when enabled), ensuring continuous timekeeping with typical accuracy of ±20 ppm over −20 to +85°C.
