Product details
Overview
R5F2L3ACBNFP#V2 from Renesas Electronics is an 88-pin LQFP 16-bit R8C/L3AB Group microcontroller with 128 KB flash, 10 KB RAM, and integrated LCD controller driving up to 8 common/56 segment outputs. It features a 20 MHz max operating frequency (2.7–5.5 V), 10-bit 20-channel ADC, dual 8-bit DACs, and real-time clock (timer RE) for battery-backed timekeeping in appliance control panels.
For engineers reviewing the R5F2L3ACBNFP#V2 datasheet, R5F2L3ACBNFP#V2 pinout, R5F2L3ACBNFP#V2 application, or R5F2L3ACBNFP#V2 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D version), background operation (BGO) data flash capability, hardware LIN support via UART0/timer RA, and low-power stop mode consuming just 1 µA with timer RE active.
Technical Context
The R5F2L3ACBNFP#V2 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory architecture includes 128 KB program ROM and no data flash (B-group variant), distinguishing it from A-group parts which feature 1 KB × 4 data flash with BGO.
It integrates six timer modules (RA–RG), two UARTs, one I²C-capable serial interface (UART2), LIN hardware support, 20-channel 10-bit ADC with sweep mode, dual 8-bit DACs, two comparators, and a full-featured LCD controller with integrated voltage multiplier and regulator - all operating within a single-chip 52-pin LQFP package.

FAQ
What is the operating temperature range for R5F2L3ACBNFP#V2?
R5F2L3ACBNFP#V2 is rated for -40°C to +85°C ambient operation (D version), making it suitable for industrial environments and outdoor consumer equipment where thermal extremes occur. This specification is confirmed in Table 1.7 of the preliminary datasheet REJ03B0243-0030 Rev.0.30 and applies across all operating modes including power-off with timer RE enabled.
Does R5F2L3ACBNFP#V2 include data flash memory?
No, R5F2L3ACBNFP#V2 does not include data flash memory. As a B-group device (indicated by "B" in the part number), it lacks the 1 KB × 4 data flash with background operation (BGO) found in A-group variants like R5F2L3ACANFP#V2. Its nonvolatile storage consists solely of 128 KB program flash, with endurance rated at 1,000 write/erase cycles.
Which package type is used for R5F2L3ACBNFP#V2?
R5F2L3ACBNFP#V2 uses a 100-pin LQFP package (PLQP0100KB-A), as specified in Table 1.15 of the R8C/L3x Group datasheet REJ03B0243-0030 Rev.0.30. This package measures 14 mm × 14 mm with 0.5 mm lead pitch and includes an exposed thermal pad for enhanced heat dissipation in continuous operation.
Can R5F2L3ACBNFP#V2 drive a 448-segment LCD display?
Yes, R5F2L3ACBNFP#V2 can drive up to 448 segments (8 commons × 56 segments) using its integrated LCD controller. The device provides dedicated VL1–VL4 bias outputs and supports 1/2, 1/3, and 1/4 bias configurations with static, 1/2, 1/3, 1/4, and 1/8 duty cycles - eliminating need for external LCD bias ICs in compliant display designs.
What debug interface does R5F2L3ACBNFP#V2 support?
R5F2L3ACBNFP#V2 supports Renesas' on-chip debug interface via the dedicated FINE pin, enabling full-featured debugging including flash programming, real-time variable monitoring, and breakpoint execution. This interface is compatible with Renesas E2 emulator and standard JTAG/SWD adapters supporting R8C architecture.
