Renesas R5F213MAQNNP#U0

Overview

R5F213MAQNNP from Renesas Electronics is a 96 KB flash, 7 KB RAM, 2.4 GHz IEEE 802.15.4-compliant RF microcontroller with integrated R8C CPU core, AES-128 encryption engine, and 40-pin HWQFN package. It delivers −95 dBm RX sensitivity, 0 dBm TX output, and operates from 1.8–3.6 V across −20°C to +85°C for low-power wireless sensor node applications.

For engineers reviewing the R5F213MAQNNP datasheet, R5F213MAQNNP pinout, R5F213MAQNNP application, or R5F213MAQNNP equivalent, key selection criteria include IEEE 802.15.4 baseband compliance, on-chip RF transceiver integration, background operation (BGO) data flash, multi-mode power management (down to 2 µA in stop mode), and hardware AES acceleration for secure mesh networking.

Technical Context

The R5F213MAQNNP integrates an R8C CPU core with 16×16→32-bit multiplier and 69 interrupt vectors, executing instructions in as little as 62.5 ns at 16 MHz. Its RF subsystem includes dedicated 2.4 GHz transceiver circuitry with IFRXTP/IFRXTN differential IF inputs, RFIOP/RFION RF I/O pins, and internal regulators (VREG1–VREG4) for analog/PLL/IF/PA blocks.

It implements a full IEEE 802.15.4 MAC layer in hardware: 127-byte TX/RX RAM buffers, automatic ACK response, 26-bit timer with three compare channels, and baseband timing synchronized to the 16 MHz XIN crystal. The device supports BGO data flash (1 KB × 4 blocks) and debug via on-chip debug interface.

FAQ

What is the maximum operating frequency and voltage range for the R5F213MAQNNP?

The R5F213MAQNNP operates at up to 16 MHz BCLK with VCC = 2.7–3.6 V, 8 MHz with VCC = 2.15–3.6 V, or 4 MHz with VCC = 1.8–3.6 V. Its RF section requires VCCRF = 1.8–3.6 V and supports full functionality across this range, including −95 dBm RX sensitivity and 0 dBm TX output at all valid supply voltages.

Does the R5F213MAQNNP support over-the-air (OTA) firmware updates?

Yes, the R5F213MAQNNP supports OTA firmware updates using its background operation (BGO) data flash feature. With 1 KB × 4 blocks of data flash, new firmware images can be written while the main program executes from program ROM-enabling seamless, non-disruptive field upgrades without halting RF communication or sensor functions.

How does the R5F213MAQNNP handle antenna switching between transmit and receive modes?

The R5F213MAQNNP uses the ASW (antenna switch control) pin-a dedicated active-high output-to drive external SPDT antenna switches. This pin is synchronized with RF state transitions, ensuring clean isolation between TX and RX paths. No software intervention is needed; ASW timing is managed automatically by the RF baseband controller.

What debug and programming interfaces are available on the R5F213MAQNNP?

The R5F213MAQNNP supports on-chip debug via Renesas' E1/E20 emulators using the standard 6-pin FINE interface (RESET, MODE, VCC, VSS, TDI, TDO). It also features an on-board flash rewrite function, allowing in-system programming through UART0 or dedicated debug pins without requiring external programmers.

Can the R5F213MAQNNP operate without an external crystal?

No-the R5F213MAQNNP requires both the 16 MHz XIN/XOUT crystal for main system clock and the 32 kHz XCIN/XCOUT crystal for real-time clock and low-power wake-up. The low-speed on-chip oscillator is only used for the watchdog timer and cannot replace either crystal for RF or timing-critical operations.
