Product details
Overview
R5F212AASNLG#U0 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, featuring 96 KB flash ROM, 7 KB RAM, and a 64-pin FLGA package (PTLG0064JA-A). It integrates a 16×16-bit hardware multiplier, 12-channel 10-bit ADC, dual 8-bit DACs, three UARTs, I²C/SSU, LIN module, and six timer units including PWM-capable Timer RD and real-time clock Timer RE - deployed in consumer appliance motor control and sensor interface applications.
For engineers reviewing the R5F212AASNLG#U0 datasheet, R5F212AASNLG#U0 pinout, R5F212AASNLG#U0 application, or R5F212AASNLG#U0 equivalent, key selection criteria include its -20°C to +85°C operating range (N version), 0.65 mm pitch 6×6 mm FLGA package, on-chip debug support, and absence of data flash (distinguishing it from R8C/2B Group variants).
Technical Context
The R5F212AASNLG#U0 implements the R8C/Tiny CPU core with 89 fundamental instructions and minimum instruction execution time of 50 ns at 20 MHz (VCC = 3.0–5.5 V). Its memory architecture separates user ROM (96 KB flash) from 7 KB SRAM, with no on-chip data flash - confirming its R8C/2A Group identity per Renesas documentation.
Peripheral integration includes Timer RD (16-bit × 2, 6-pin PWM, complementary/triangular/sawtooth modulation), hardware LIN via UART0 and Timer RA, and dual DAC outputs for analog actuator control. Clock sources comprise XIN (up to 20 MHz), high-/low-speed on-chip oscillators, and 32 kHz XCIN for RTC operation in stop mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F212A8SNLG | 64 KB flash, 3 KB RAM, same package and peripheral set - lacks 32 KB ROM capacity and 4 KB RAM headroom of R5F212AASNLG#U0. | Suitable for simpler firmware with smaller code footprint and reduced data buffering needs. | Select when application logic fits within 64 KB and requires identical pinout/peripherals at lower cost. |
| R5F212BASNLG | Same 96 KB flash and 7 KB RAM, but adds 2 KB on-chip data flash (1 KB × 2 blocks) - not present in R5F212AASNLG#U0. | Required for applications needing nonvolatile parameter storage (e.g., calibration data, user settings) without external EEPROM. | Choose only if data flash endurance (10,000 cycles) and retention are mandatory; otherwise R5F212AASNLG#U0 offers lower cost and same core functionality. |
Compared with R5F212A8SNLG, R5F212AASNLG#U0 provides 32 KB additional flash and 4 KB more RAM for complex control algorithms and data logging, while R5F212BASNLG trades off higher cost and marginally increased power for integrated data flash - making R5F212AASNLG#U0 optimal for ROM-bound, RAM-intensive embedded control without persistent parameter storage needs.

The R5F212AASNLG#U0 supports a maximum external crystal frequency of 20 MHz at VCC = 3.0–5.5 V, achieving a minimum instruction execution time of 50 ns. Its internal high-speed on-chip oscillator is adjustable and usable as a clock source when external crystals are omitted, though with reduced accuracy.
Does the R5F212AASNLG#U0 include on-chip data flash memory?
No, the R5F212AASNLG#U0 belongs to the R8C/2A Group and contains only program flash memory (96 KB) and SRAM (7 KB). Data flash (1 KB × 2 blocks) is exclusive to the R8C/2B Group, such as R5F212BASNLG - confirmed in Renesas documentation Tables 1.1–1.4 and Product List Table 1.5.
What package type does the R5F212AASNLG#U0 use, and what are its mechanical dimensions?
The R5F212AASNLG#U0 uses the 64-pin FLGA package PTLG0064JA-A (formerly 64F0G), measuring 6 mm × 6 mm with 0.65 mm pin pitch and an exposed thermal pad. This compact, fine-pitch package supports high-density PCB layouts typical in consumer appliance mainboards.
Which timers in the R5F212AASNLG#U0 support complementary PWM output for 3-phase motor control?
Timer RD is the only timer in the R5F212AASNLG#U0 that supports complementary PWM mode, generating synchronized three-phase waveforms across six output pins (TRDIOA0–TRDIOD1) with configurable dead-time - essential for driving IGBT or MOSFET half-bridge stages in BLDC and PMSM inverters.
Is the R5F212AASNLG#U0 qualified for automotive applications?
No, the R5F212AASNLG#U0 is an N-version device rated for -20°C to +85°C ambient temperature and classified as "Standard" quality grade per Renesas - intended for consumer electronics, office equipment, and industrial robots. Automotive use requires D-version (-40°C to +85°C) or "High Quality" grade parts with explicit qualification documentation.
