Renesas R5F213G2MNNP#U0

Overview

R5F213G2MNNP from Renesas Electronics is an 8-bit R8C CPU core microcontroller in a 24-pin HWQFN package, featuring 8 KB program flash, 1 KB RAM, and 4 × 1 KB data flash blocks with background operation (BGO). It delivers 50 ns minimum instruction execution at 20 MHz (V_CC = 2.7–5.5 V), integrates dual 10-bit A/D converters (8 channels), dual 8-bit D/A outputs, LIN hardware module, and real-time clock (Timer RE) - deployed in consumer audio equipment and office automation control systems.

For engineers reviewing the R5F213G2MNNP datasheet, R5F213G2MNNP pinout, R5F213G2MNNP application, or R5F213G2MNNP equivalent, key selection considerations include its 24-pin PWQN0024KC-A package, -20°C to +85°C operating range (N version), integrated LIN transceiver support via UART0/Timer RA, and BGO-enabled in-system reprogramming of data flash without halting CPU execution.

Technical Context

The R5F213G2MNNP implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte (00000h–FFFFFh), with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash allocated at 03000h–03FFFh across four independent 1 KB blocks.

Peripheral integration includes three independent timers (RA/RB/RC), Timer RE for RTC, UART0/UART2 with I²C mode, SSU, LIN module, 10-bit A/D converter with sweep mode, two 8-bit D/A converters, dual comparators (A/B), voltage detection circuits (VDET0/VDET1), and DTC for autonomous data transfers - all managed via dedicated SFRs mapped to 0000h–02FFFh address space.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F213G2MNNP?

The R5F213G2MNNP operates up to 20 MHz at V_CC = 2.7–5.5 V, and down to 5 MHz at V_CC = 1.8–5.5 V. This dual-frequency capability allows flexible system design: high-speed execution for control loops at nominal voltage, and extended low-voltage operation for brown-out resilience. The R5F213G2MNNP maintains full peripheral functionality across this entire range, including A/D conversion and UART communication.

Does the R5F213G2MNNP support in-application programming of its data flash memory?

Yes, the R5F213G2MNNP supports Background Operation (BGO) for data flash, enabling CPU execution to continue uninterrupted during erase or write cycles. This feature is critical for applications requiring runtime parameter storage or firmware patching - for example, saving user preferences in audio equipment without disrupting playback. The R5F213G2MNNP's four independent 1 KB data flash blocks allow wear-leveling and atomic updates.

How many analog-to-digital converter channels does the R5F213G2MNNP provide, and what is their resolution?

The R5F213G2MNNP integrates a single 10-bit A/D converter with eight input channels (AN0–AN11, with some shared pins). It supports sweep mode for automatic sequential conversion and includes sample-and-hold circuitry to maintain signal integrity during conversion. This capability meets requirements for sensor monitoring in appliances and audio level detection - all without external signal conditioning components.

Can the R5F213G2MNNP generate PWM signals, and which timers support this function?

Yes, the R5F213G2MNNP generates PWM via Timer RB (programmable waveform generation mode) and Timer RC (PWM and PWM2 modes, supporting up to three simultaneous outputs). Timer RB provides single-channel variable-duty-cycle output ideal for LED dimming, while Timer RC enables multi-phase motor control or synchronized actuator drive. Both timers use dedicated prescalers and capture/compare registers for precise duty-cycle and frequency control - essential for R5F213G2MNNP-based motor and lighting applications.

What is the purpose of the MODE pin on the R5F213G2MNNP, and how should it be configured?

The MODE pin on the R5F213G2MNNP must be externally pulled high to V_CC via a resistor to select single-chip mode - the only supported configuration for normal operation. In this mode, the R5F213G2MNNP uses internal program ROM and executes from its 1 Mbyte address space. Leaving MODE floating or pulling it low may cause undefined boot behavior or failure to initialize, so proper pull-up is mandatory for reliable R5F213G2MNNP deployment.
