Product details
Overview
R5F212AASDFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2A Group, designed for embedded control in cost-sensitive industrial and consumer systems. It features 96 KB flash ROM, 7 KB RAM, 12-channel 10-bit A/D converter, dual 8-bit D/A converters, and operates from 2.2 V to 5.5 V across -40°C to +85°C (D version). It supports LIN bus via hardware module (UART0 + Timer RA) and delivers 50 ns minimum instruction execution at 20 MHz.
For engineers reviewing the R5F212AASDFP#V2 datasheet, R5F212AASDFP#V2 pinout, R5F212AASDFP#V2 application, or R5F212AASDFP#V2 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064KB-A) package, integrated real-time clock (Timer RE), low-power stop mode (0.65 µA), and on-chip debug capability - all critical for appliance motor control, sensor interface, and battery-powered HMI designs.
Technical Context
The R5F212AASDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient arithmetic. Its memory architecture includes user-programmable flash ROM (96 KB) and SRAM (7 KB), with no on-chip data flash - distinguishing it from the R8C/2B Group.
Peripheral integration includes three UARTs, one I²C/SSU shared channel, hardware LIN support, six independent timers (RA–RF) with PWM, input capture, and complementary three-phase output modes, plus 55 CMOS I/O ports (8 high-current drive). Clock sources comprise XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz), and programmable high-/low-speed on-chip oscillators.
Key Specifications

The R5F212AASDFP#V2 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 on-chip high-speed oscillator is adjustable and usable up to 20 MHz, while the low-speed oscillator runs at 32 kHz for RTC functions. The CPU core executes instructions at speeds directly tied to the selected clock source and divider settings.
Does the R5F212AASDFP#V2 include on-chip data flash memory?
No, the R5F212AASDFP#V2 belongs to the R8C/2A Group and contains only program flash ROM (96 KB). It does not include dedicated data flash. For data logging or field-updatable parameters, external EEPROM or FRAM is required. In contrast, the R8C/2B Group part R5F212BASDFP#V2 integrates 2 KB of data flash (1 KB × 2 blocks).
Which package type does the R5F212AASDFP#V2 use?
The R5F212AASDFP#V2 uses the 64-pin LQFP package with code PLQP0064KB-A: 0.5 mm pin pitch, 10 mm × 10 mm body size, and standard gull-wing leads. This package is fully compatible with industry-standard reflow profiles and automated optical inspection (AOI) systems used in high-volume manufacturing.
Can the R5F212AASDFP#V2 support hardware LIN communication?
Yes, the R5F212AASDFP#V2 includes a dedicated hardware LIN module implemented using UART0 and Timer RA. It supports LIN 2.0/2.1 physical layer signaling and protocol timing without CPU intervention, enabling reliable slave-node operation in automotive body control and industrial networked sensors.
What are the low-power modes supported by the R5F212AASDFP#V2?
The R5F212AASDFP#V2 supports wait mode (2.1 µA at 3.0 V with 32 kHz RTC active) and stop mode (0.65 µA at 3.0 V). Both modes retain RAM content and allow wake-up via external interrupt, timer compare match, or serial receive event. These modes are validated for the D-version temperature range (-40°C to +85°C).
