Product details
Overview
R5F212ACSNLG#U0 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU with 128 KB flash ROM, 7.5 KB RAM, and 64-pin FLGA (PTLG0064JA-A) package. It integrates a 16×16-bit multiplier, 12-channel 10-bit ADC, dual 8-bit DACs, three UARTs, I²C/SSU, hardware LIN, and six timer modules including PWM-capable Timer RD and real-time clock Timer RE. It targets embedded control in consumer appliances requiring low-power operation down to 0.65 µA in stop mode.
For engineers reviewing the R5F212ACSNLG#U0 datasheet, R5F212ACSNLG#U0 pinout, R5F212ACSNLG#U0 application, or R5F212ACSNLG#U0 equivalent, key selection considerations include its 64-pin FLGA footprint, -20°C to +85°C N-version temperature grade, on-chip debug support, and absence of data flash (R8C/2A Group identity confirmed by part number suffix 'A' and no data flash in spec tables).
Technical Context
The R5F212ACSNLG#U0 implements the R8C/Tiny CPU core with 89 fundamental instructions and executes at 50 ns minimum instruction time (20 MHz XIN, 3.0–5.5 V). Its memory subsystem includes user-programmed flash ROM and SRAM, with no on-chip data flash-distinguishing it from R8C/2B Group variants like R5F212BCSNLG.
Peripheral integration centers on deterministic timing control: Timer RD provides six-PWM output with complementary and three-phase waveform generation; UART0 pairs with Timer RA for hardware LIN bus compliance; and the 12-channel ADC supports sample-and-hold for synchronized multi-signal acquisition in motor or sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F212ACSNFP#U0 | Same core, memory, and peripherals; differs only in 64-pin LQFP (PLQP0064KB-A) package with 0.5 mm pitch and 10 mm × 10 mm body. | Preferred where board space permits larger footprint and hand-soldering or legacy LQFP tooling is used. | Select for compatibility with existing LQFP layouts or when thermal dissipation via exposed pad is not required. |
| R5F212ACSDFP#U0 | Identical functionality and package as R5F212ACSNFP#U0, but rated for -40°C to +85°C (D version) instead of -20°C to +85°C (N version). | Required for industrial or automotive cabin applications subject to extended cold-start conditions. | Choose when operating ambient exceeds 85°C or drops below -20°C; otherwise, R5F212ACSNLG#U0 offers optimal cost/performance for consumer-grade use. |
Compared with R5F212ACSNFP#U0, the R5F212ACSNLG#U0 saves 30% board area via FLGA packaging but requires fine-pitch reflow; versus R5F212ACSDFP#U0, it trades extended temperature range for lower unit cost in climate-controlled environments.

FAQ
What is the maximum operating frequency of the R5F212ACSNLG#U0?
The R5F212ACSNLG#U0 supports a maximum external crystal frequency of 20 MHz at VCC = 3.0–5.5 V, achieving a 50 ns minimum instruction execution time. Its on-chip high-speed oscillator is adjustable but does not exceed this frequency. The MCU must be operated within these limits to ensure timing compliance across all peripherals, including Timer RD PWM and ADC sampling windows.
Does the R5F212ACSNLG#U0 include on-chip data flash memory?
No, the R5F212ACSNLG#U0 belongs to the R8C/2A Group and contains no data flash. It has 128 KB of program flash ROM and 7.5 KB of RAM only. Data flash (1 KB × 2 blocks) is exclusive to R8C/2B Group parts such as R5F212BCSNLG. This distinction is encoded in the second letter of the part number: 'A' = R8C/2A (no data flash), 'B' = R8C/2B (with data flash).
Which package type does the R5F212ACSNLG#U0 use, and what are its key mechanical features?
The R5F212ACSNLG#U0 uses the 64-pin FLGA package (PTLG0064JA-A): 0.65 mm pin pitch, 6 mm × 6 mm body size, and non-electrical exposed pad. It is distinct from LQFP variants (e.g., R5F212ACSNFP) and requires reflow soldering with profile optimized for fine-pitch leadless packages. Pin 1 location is marked by a dot on the top surface per Figure 1.5.
How many UART interfaces does the R5F212ACSNLG#U0 support, and what are their primary use cases?
The R5F212ACSNLG#U0 integrates three independent UART modules (UART0, UART1, UART2). UART0 is hardware-assigned to LIN physical layer operation with Timer RA; UART1 serves as a general-purpose host interface (e.g., to Wi-Fi or Bluetooth modules); UART2 supports auxiliary functions like firmware updates or debug logging. All support standard asynchronous framing and programmable baud rates.
What is the operating temperature range specified for the R5F212ACSNLG#U0?
The R5F212ACSNLG#U0 is an N-version device rated for an operating ambient temperature range of -20°C to +85°C. This is indicated by the 'N' in the part number suffix and aligns with Renesas' "Standard" quality grade, intended for consumer and office equipment-not automotive under-hood or industrial extended-range applications.
