Product details
Overview
R5F2L3ACBNFP#U1 from Renesas Electronics is an 88-pin LQFP 16-bit R8C/L3AB Group microcontroller with 128 KB flash, 10 KB RAM, integrated LCD controller (up to 8 COM / 56 SEG), and 20-channel 10-bit ADC - designed for embedded control in consumer appliance front panels requiring low-power operation and direct segment-driven display interfacing.
For engineers reviewing the R5F2L3ACBNFP#U1 datasheet, R5F2L3ACBNFP#U1 pinout, R5F2L3ACBNFP#U1 application, or R5F2L3ACBNFP#U1 equivalent, key selection considerations include its -40°C to +85°C D-grade industrial temperature rating, background operation (BGO) support for data flash, real-time clock (timer RE), and hardware LIN interface using UART0 and timer RA.
Technical Context
The R5F2L3ACBNFP#U1 implements the R8C CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient signal processing and control loop execution. It operates across a 1.8–5.5 V supply range and supports multiple clock sources: external XIN (up to 20 MHz), 32 kHz XCIN, and on-chip high/low-speed oscillators with selectable frequency division (1/2/4/8/16).
Its peripheral set includes four 16-bit timers (RD, RC, RG), two 8-bit timers (RA, RB), a real-time clock (RE), UART0/1/2 with I²C and LIN modes, SSU, DTC, and dual 8-bit DACs - all coordinated via a 7-level priority interrupt system with 69 vectors and 16 external interrupt pins (8 INT + 8 key input).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2L3ACANFP#U1 | A-group variant with 1 KB × 4 data flash and BGO; same package, memory size, and peripherals | Requires background flash updates during runtime (e.g., firmware logging); not needed for static configuration storage | Select R5F2L3ACANFP#U1 only if data flash write/erase during operation is required; otherwise R5F2L3ACBNFP#U1 offers cost and endurance advantage |
| R5F2L38CBNFP#U0 | 68-pin LQFP R8C/L38B Group part: 128 KB flash, 10 KB RAM, 16-channel ADC, 48-segment LCD, no LIN module | Lacks hardware LIN and 4 extra ADC channels; smaller footprint but fewer I/O (68 vs. 88 pins) | Choose R5F2L38CBNFP#U0 for space-constrained designs where LIN is unnecessary and segment count ≤48 suffices |
Compared with R5F2L3ACANFP#U1, R5F2L3ACBNFP#U1 trades data flash for higher endurance and lower cost, while R5F2L38CBNFP#U0 reduces pin count and peripheral count to fit compact UIs without LIN dependency.

FAQ
What is the operating temperature range for R5F2L3ACBNFP#U1?
R5F2L3ACBNFP#U1 is a D-version device rated for -40°C to +85°C ambient operation, meeting Renesas' industrial-grade quality classification. This specification is validated per the preliminary datasheet REJ03B0243-0030 and applies to all electrical characteristics unless otherwise noted in derating tables.
Does R5F2L3ACBNFP#U1 include data flash memory?
No, R5F2L3ACBNFP#U1 belongs to the B-group variant and does not include data flash. Unlike A-group parts (e.g., R5F2L3ACANFP#U1), it provides only program ROM (128 KB) and RAM (10 KB). Data retention must be handled externally or via EEPROM emulation in program flash.
Which package type is used for R5F2L3ACBNFP#U1?
R5F2L3ACBNFP#U1 uses a 100-pin LQFP package designated PLQP0100JA-A - a 14 mm × 14 mm body with 0.5 mm lead pitch and standard RoHS-compliant finish. Pin assignments match Figures 1.17 and Table 1.15 in the R8C/L3AB Group datasheet.
Can R5F2L3ACBNFP#U1 drive a 56-segment LCD display directly?
Yes, R5F2L3ACBNFP#U1 integrates a full LCD controller supporting up to 8 common and 56 segment outputs, with on-chip voltage multiplier and regulator. No external bias IC is required for static or multiplexed (1/2, 1/3, 1/4) LCDs within its voltage and current limits.
Is hardware LIN functionality available on R5F2L3ACBNFP#U1?
Yes, R5F2L3ACBNFP#U1 includes a dedicated hardware LIN module compliant with LIN 2.0/2.1, implemented using UART0 and timer RA. This enables deterministic frame transmission/reception without CPU intervention, reducing firmware overhead versus software-based LIN stacks.
