Product details
Overview
R5F2L3ACANFP#U1 from Renesas Electronics is a 16-bit R8C/L3AA Group microcontroller featuring 128 KB flash program ROM, 10 KB RAM, and integrated LCD controller driving up to 8 common and 56 segment outputs. It operates at up to 20 MHz (VCC = 2.7–5.5 V), supports 88 programmable CMOS I/O ports with 16 high-current drive pins, and includes UART0/1/2, I²C, LIN, 20-channel 10-bit ADC, dual 8-bit DACs, and real-time clock (Timer RE). It targets embedded control in appliance front panels and industrial HMI displays.
For engineers reviewing the R5F2L3ACANFP#U1 datasheet, R5F2L3ACANFP#U1 pinout, R5F2L3ACANFP#U1 application, or R5F2L3ACANFP#U1 equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C D-version operating temperature, background operation (BGO) data flash capability, and hardware LIN support using Timer RA and UART0 - all confirmed for this exact part number per Renesas preliminary specification REJ03B0243-0030.
Technical Context
The R5F2L3ACANFP#U1 implements the R8C CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier. Its memory architecture includes 128 KB on-chip flash (1,000 write/erase endurance) and 10 KB RAM, with data flash absent in the B-series variants but confirmed unavailable in this A-series part per Table 1.1.
Peripheral integration includes Timer RD (16-bit ×2, supporting 3-phase PWM with complementary outputs), UART2 with I²C-bus mode, and an LCD controller with integrated voltage multiplier and regulator. The device uses four clock sources: XIN (up to 20 MHz), XCIN (32 kHz), and two on-chip oscillators - all feeding into a programmable frequency divider with ratios of 1/2/4/8/16.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2L3ABNFP | Same R8C/L3AB Group, 128 KB ROM/10 KB RAM, but N-version (-20°C to +85°C) and no data flash; identical pinout and peripherals. | Restricted to commercial indoor environments; unsuitable for outdoor or industrial enclosures requiring extended temperature range. | Select R5F2L3ABNFP only if ambient temperature stays above -20°C and data flash functionality is unnecessary. |
| R5F2L36CANFP | R8C/L36A Group, 128 KB ROM/10 KB RAM, 64-pin LQFP, 52 I/O pins, no LCD controller, no LIN module, but includes data flash (1 KB × 4 blocks). | Targeted at compact control nodes without display requirements; lacks hardware LCD and LIN, limiting use in HMI or automotive subsystems. | Choose R5F2L36CANFP when board space is constrained and display/LIN are not needed - but expect redesign for 64-pin footprint and missing peripherals. |
Compared with R5F2L3ACANFP#U1, R5F2L3ABNFP trades industrial temperature range for identical feature set in commercial settings, while R5F2L36CANFP sacrifices LCD/LIN capability and I/O count for smaller package and data flash - making neither a drop-in replacement but viable alternatives under specific design constraints.

FAQ
What is the operating temperature range for R5F2L3ACANFP#U1?
R5F2L3ACANFP#U1 is the D-version part, rated for -40°C to +85°C operating ambient temperature. This qualification meets industrial and automotive cabin requirements where thermal stability is critical. The part number suffix "D" explicitly denotes this extended range, as defined in Renesas documentation REJ03B0243-0030.
Does R5F2L3ACANFP#U1 include data flash memory?
No, R5F2L3ACANFP#U1 does not include data flash memory. It belongs to the R8C/L3AA Group A-series, which - per Table 1.1 in the Renesas preliminary spec - provides program ROM only. Data flash (1 KB × 4 blocks with BGO) is present only in the A-series groups (L35A/L36A/L38A/L3AA), but R5F2L3ACANFP#U1's product list entry confirms absence of data flash in its memory configuration.
Which package type is used for R5F2L3ACANFP#U1?
R5F2L3ACANFP#U1 uses a 100-pin LQFP package (PLQP0100JA-A), measuring 14 mm × 14 mm with 0.5 mm pitch. This matches the R8C/L3AA Group's highest I/O count variant and is distinct from the 52-pin (L35x), 64-pin (L36x), or 80-pin (L38x) packages used by other family members.
Can R5F2L3ACANFP#U1 drive a 4-layer LCD directly?
Yes, R5F2L3ACANFP#U1 integrates a full LCD controller with on-chip voltage multiplier supporting 1/2, 1/3, and 1/4 bias configurations - enabling direct drive of 4-layer segment LCDs without external bias generators. Its 8 common and 56 segment outputs match standard 4-layer glass specifications.
Is hardware LIN functionality available on R5F2L3ACANFP#U1?
Yes, R5F2L3ACANFP#U1 includes a dedicated hardware LIN module compliant with LIN 2.1, implemented using UART0 and Timer RA as specified in Section 1.1.2 of the Renesas preliminary datasheet. This offloads protocol handling from firmware and ensures deterministic timing for automotive body electronics applications.
