Renesas R5F213M8QNNP#U0

Overview

R5F213M8QNNP from Renesas Electronics is a 64 KB flash, 6 KB RAM, 40-pin HWQFN single-chip MCU integrating an IEEE 802.15.4-compliant 2.4 GHz RF transceiver, R8C CPU core, AES-128 encryption engine, and background operation (BGO) data flash. It operates at up to 16 MHz with 1.8–3.6 V supply and supports low-power wait/stop modes down to 2 µA. It targets wireless sensor nodes in consumer electronics.

For engineers reviewing the R5F213M8QNNP datasheet, R5F213M8QNNP pinout, R5F213M8QNNP application, or R5F213M8QNNP equivalent, key selection criteria include its integrated 2.4 GHz RF front-end (−95 dBm sensitivity, 0 dBm output), on-chip AES-128 acceleration, 40-pin 6×6 mm HWQFN package with dedicated RF power domains, and support for IEEE 802.15.4 MAC layer implementation in firmware.

Technical Context

The R5F213M8QNNP implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and 20-bit address space (1 Mbyte). Its RF subsystem includes baseband logic with 127-byte TX/RX RAM buffers, automatic ACK response, and 26-bit timer with three compare channels.

It integrates dual clock systems: high-speed XIN (16 MHz crystal), low-speed XCIN (32 kHz crystal), and low-power on-chip oscillator (15.6 kHz). Power management includes voltage detection (VDD monitoring), multiple low-power modes (wait mode at 4.5 µA, stop mode at 2 µA), and separate analog/RF power domains (VCCRF, VREG1–VREG4).

FAQ

What is the maximum operating frequency and supply voltage range for the R5F213M8QNNP?

The R5F213M8QNNP operates at up to 16 MHz with a supply voltage range of 1.8 V to 3.6 V for both digital (VCC) and RF (VCCRF) domains. At 16 MHz, it requires VCC = VCCRF = 2.7–3.6 V; lower frequencies (8 MHz, 4 MHz) extend operation down to 2.15 V and 1.8 V respectively, enabling flexible power/performance trade-offs in battery-powered designs.

Does the R5F213M8QNNP support hardware-accelerated AES encryption?

Yes, the R5F213M8QNNP includes a dedicated AES-128 encryption/decryption engine that performs full-block operations in under 10 µs. This hardware accelerator offloads cryptographic processing from the R8C CPU, enabling secure IEEE 802.15.4 frame encryption without compromising real-time responsiveness or increasing firmware size.

What RF performance specifications does the R5F213M8QNNP provide?

The R5F213M8QNNP delivers −95 dBm receiver sensitivity and 0 dBm transmit output power across the 2405–2480 MHz ISM band. Its RF baseband includes 127-byte TX/RX RAM, automatic ACK response, and 26-bit timer with three compare channels-enabling robust, low-latency 802.15.4 MAC layer implementation directly in firmware.

How does the R5F213M8QNNP manage power in low-power modes?

The R5F213M8QNNP supports multiple low-power states: stop mode draws just 2 µA (all clocks off), wait mode with XCIN clock and peripherals off consumes 4.5 µA, and RF idle mode draws 7.5 mA at 16 MHz. Its dual clock domains and isolated RF power rails allow selective subsystem shutdown while maintaining real-time wake-up capability via INT0/INT3 or RF events.

What package type and pin count does the R5F213M8QNNP use?

The R5F213M8QNNP uses a 40-pin HWQFN package (package code PWQN0040KB-A), measuring 6 mm × 6 mm with 0.5 mm pitch and an exposed die pad (DIEGND) that must be soldered to the PCB ground plane for thermal and electrical performance. This compact, thermally efficient package supports high-density wireless module layouts.
