Product details
Overview
R5F212C7SNFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in an 80-pin LQFP package, featuring 48 KB flash ROM, 2.5 KB RAM, and operation from 2.2 V to 5.5 V. It integrates a 16×16-bit hardware multiplier, 20-channel 10-bit A/D converter, dual 8-bit D/A outputs, and six timer modules (RA–RF) supporting PWM, input capture, and real-time clock functions. It targets embedded control in consumer appliances requiring low-power operation down to 0.65 µA in stop mode.
For engineers reviewing the R5F212C7SNFP#V2 datasheet, R5F212C7SNFP#V2 pinout, R5F212C7SNFP#V2 application, or R5F212C7SNFP#V2 equivalent, key selection considerations include its -20°C to +85°C industrial temperature grade (N version), 80-pin PLQP0080KB-A package with 0.5 mm pitch, on-chip debug support, and absence of data flash-distinguishing it from R8C/2D Group variants.
Technical Context
The R5F212C7SNFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and single-chip 1 Mbyte address space. Its clock system includes XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz), and high-/low-speed on-chip oscillators with frequency adjustment.
Peripheral integration includes three UARTs, one I2C bus (shared with SSU), hardware LIN via UART0 and Timer RA, and a 15-bit watchdog timer with selectable reset start. Power management supports wait and stop modes with sub-µA current draw at 3.0 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F212C8SNFP | 64 KB flash ROM, 3 KB RAM - same package, peripherals, and temperature grade | Required where firmware size exceeds 48 KB or additional RAM buffers are needed for protocol stacks | Select when future firmware expansion or larger data logging buffers are anticipated |
| R5F212D7SNFP | Includes 2 KB data flash (1 KB × 2 blocks); otherwise identical ROM/RAM and peripheral set | Suitable 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 required for field-updatable configuration |
Compared with R5F212C7SNFP#V2, R5F212C8SNFP offers headroom for firmware growth while maintaining identical I/O and timing behavior, whereas R5F212D7SNFP adds data flash at the cost of reduced program flash endurance (1,000 vs. 100 erase cycles) - making R5F212C7SNFP#V2 optimal for fixed-function, cost-sensitive control tasks.

FAQ
What is the maximum operating frequency of the R5F212C7SNFP#V2?
The R5F212C7SNFP#V2 supports a maximum XIN clock frequency of 20 MHz at VCC = 3.0 V to 5.5 V, delivering a minimum instruction execution time of 50 ns. At lower supply voltages (2.2 V to 2.7 V), the maximum supported frequency reduces to 5 MHz for guaranteed operation.
Does the R5F212C7SNFP#V2 include on-chip data flash memory?
No, the R5F212C7SNFP#V2 belongs to the R8C/2C Group and contains only program flash memory (48 KB). It does not include dedicated data flash. For data flash functionality, consider the R8C/2D Group variant R5F212D7SNFP, which provides 1 KB × 2 blocks of data flash.
What are the key differences between the R5F212C7SNFP#V2 and R5F212C7SDFP?
The R5F212C7SNFP#V2 is rated for -20°C to +85°C (N version), while R5F212C7SDFP is the D version rated for -40°C to +85°C. All electrical specifications, peripherals, and pinout are identical-only the extended temperature range differs, making the D version suitable for automotive under-hood or industrial outdoor environments.
Can the R5F212C7SNFP#V2 operate from a 3.3 V supply?
Yes, the R5F212C7SNFP#V2 operates across 2.2 V to 5.5 V, fully supporting 3.3 V nominal supply. At 3.0 V, it achieves 10 MHz operation with 100 ns instruction timing; at 3.3 V, it can run up to 20 MHz if VCC remains within the 3.0–5.5 V specification band defined in the datasheet.
Which development tools support the R5F212C7SNFP#V2?
The R5F212C7SNFP#V2 is supported by Renesas' High-performance Embedded Workshop (HEW) IDE and the E8/E8a in-circuit emulators. Its on-chip debug interface allows programming and debugging via the standard 10-pin JTAG connector without requiring external debug hardware beyond the emulator pod.
