Renesas R5F213M6QNNP#U0

Overview

R5F213M6QNNP from Renesas Electronics is a 16-bit R8C CPU-based single-chip microcontroller with integrated 2.4 GHz IEEE 802.15.4 RF transceiver, 32 KB program flash, 2.5 KB RAM, and 4 KB data flash (1 KB × 4 blocks). It operates at up to 16 MHz BCLK (VCC = 2.7–3.6 V), delivers −95 dBm RX sensitivity and 0 dBm TX output, and supports AES-128 encryption for secure wireless sensor node applications in consumer electronics.

For engineers reviewing the R5F213M6QNNP datasheet, R5F213M6QNNP pinout, R5F213M6QNNP application, or R5F213M6QNNP equivalent, key selection considerations include its integrated RF baseband, low-power operation modes (down to 2 µA in stop mode), hardware AES engine, 40-pin HWQFN package, and compatibility with Zigbee/RF4CE protocol stacks.

Technical Context

The R5F213M6QNNP integrates an R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its RF subsystem includes dedicated 127-byte TX/RX RAM buffers, automatic ACK response, and 26-bit timer with three compare channels for precise MAC timing.

It features dual clock domains: high-speed XIN (16 MHz crystal) for CPU/RF operation and low-frequency XCIN (32 kHz) for real-time clock and ultra-low-power wait/stop modes. The on-chip voltage regulator chain supplies separate 1.5 V rails (VREGOUT1–VREGOUT4) for RF analog, PLL, IF, and oscillator circuits to minimize noise coupling.

FAQ

What is the maximum operating frequency and voltage range for the R5F213M6QNNP?

The R5F213M6QNNP supports three operating modes: 16 MHz BCLK at VCC = 2.7–3.6 V, 8 MHz at VCC = 2.15–3.6 V, and 4 MHz at VCC = 1.8–3.6 V. The XIN clock is fixed at 16 MHz per datasheet specification. All modes maintain full RF functionality and AES acceleration.

Does the R5F213M6QNNP support over-the-air (OTA) firmware updates?

Yes, the R5F213M6QNNP supports OTA updates via its 4 KB data flash with Background Operation (BGO) capability. This allows the R5F213M6QNNP to execute application code while simultaneously rewriting data flash blocks-enabling seamless, non-interrupting firmware upgrades in deployed devices.

What RF regulatory certifications does the R5F213M6QNNP hold?

The R5F213M6QNNP itself is not pre-certified; however, Renesas provides reference designs and RF layout guidelines compliant with FCC Part 15.247, ETSI EN 300 328, and ARIB STD-T66. System-level certification requires validation of the host PCB's RF section, but the R5F213M6QNNP's integrated RF architecture simplifies compliance testing.

Can the R5F213M6QNNP operate without an external crystal?

No-the R5F213M6QNNP requires both the 16 MHz XIN/XOUT crystal for CPU and RF operation and the 32 kHz XCIN/XCOUT crystal for real-time clock and ultra-low-power modes. The on-chip oscillators are only used for watchdog timer (low-speed OCO-S) and cannot replace either crystal for main system timing.

How is AES-128 encryption implemented in the R5F213M6QNNP?

The R5F213M6QNNP includes a dedicated hardware AES-128 engine-not a software library. It performs full encryption/decryption cycles in parallel with CPU execution, accepts keys and data via memory-mapped registers, and supports ECB/CBC modes. This ensures deterministic timing and zero CPU overhead for security operations in the R5F213M6QNNP.
