Renesas R5F212BCSNFA#X6

Overview

R5F212BCSNFA#X6 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2B Group, featuring 128 KB flash program memory, 2 KB on-chip data flash (1 KB × 2 blocks), 7.5 KB RAM, and operation at up to 20 MHz (VCC = 3.0–5.5 V). It integrates 12-channel 10-bit ADC, dual 8-bit DACs, six timer modules (including three-phase PWM-capable Timer RD), LIN hardware interface, and UART/SSU/I²C serial interfaces. It targets embedded control in consumer appliances requiring low-power operation and mixed-signal integration.

For engineers reviewing the R5F212BCSNFA#X6 datasheet, R5F212BCSNFA#X6 pinout, R5F212BCSNFA#X6 application, or R5F212BCSNFA#X6 equivalent, key selection considerations include its 64-pin LQFP package (PLQP0064GA-A), -20°C to +85°C industrial temperature grade (N version), on-chip data flash endurance (10,000 erase/write cycles), real-time clock (Timer RE), and LIN bus support via UART0 and Timer RA.

Technical Context

The R5F212BCSNFA#X6 implements the R8C/Tiny CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier for efficient signal processing. Its clock system includes XIN/XOUT crystal oscillator (up to 20 MHz), high-speed/low-speed on-chip oscillators, and 32 kHz XCIN/XCOUT RTC oscillator with stop-detection capability.

Peripheral integration centers on deterministic timing control: Timer RD supports reset-synchronous and complementary PWM for motor drive, Timer RC provides 4-register capture/compare for encoder input, and the LIN module uses UART0 with Timer RA for baud rate generation and frame synchronization-enabling single-wire automotive subnetwork communication without external transceiver logic.

FAQ

What is the maximum operating frequency and supply voltage range for R5F212BCSNFA#X6?

R5F212BCSNFA#X6 operates at up to 20 MHz when supplied with 3.0–5.5 V. At lower frequencies (10 MHz, 5 MHz), it supports reduced supply voltages down to 2.2 V. This allows flexible power design across battery-powered and line-powered systems while maintaining full peripheral functionality.

Does R5F212BCSNFA#X6 include hardware LIN support, and how is it implemented?

Yes, R5F212BCSNFA#X6 includes dedicated hardware LIN support using UART0 combined with Timer RA for precise baud rate generation and frame timing. This offloads LIN protocol handling from the CPU, ensuring compliance with LIN 2.x timing requirements without software bit-banging overhead.

What are the data flash specifications and endurance for R5F212BCSNFA#X6?

R5F212BCSNFA#X6 includes 2 KB of on-chip data flash organized as two 1 KB blocks, rated for 10,000 erase/write cycles. It operates at the same VCC range (2.7–5.5 V) as program flash and supports on-board rewrite via on-chip debug interface-enabling field firmware updates and parameter storage.

Which package type and pin count does R5F212BCSNFA#X6 use?

R5F212BCSNFA#X6 uses a 64-pin LQFP package with code PLQP0064GA-A, featuring 0.8 mm pin pitch and a 14 mm × 14 mm body. This package is distinct from the FP variant (PLQP0064KB-A, 0.5 mm pitch) and supports standard surface-mount assembly processes.

What low-power modes are available on R5F212BCSNFA#X6, and what are their typical current draws?

R5F212BCSNFA#X6 supports wait mode (2.1 µA @ 3 V, 32 kHz RTC active) and stop mode (0.65 µA @ 3 V). Both modes retain RAM content and allow wake-up via external interrupt or RTC alarm. These modes enable multi-year battery life in sensor nodes and remote controls.
