Renesas R5F213MCQNNP#U0

Overview

R5F213MCQNNP from Renesas Electronics is a single-chip 2.4 GHz IEEE 802.15.4-compliant RF transceiver MCU featuring the R8C CPU core, 112 KB flash ROM, 7.5 KB RAM, and integrated AES-128 encryption. It operates across 1.8–3.6 V supply with ultra-low-power modes (2 µA in stop mode), supports 2405–2480 MHz ISM band transmission/reception, and targets wireless sensor node applications in consumer electronics.

For engineers reviewing the R5F213MCQNNP datasheet, R5F213MCQNNP pinout, R5F213MCQNNP application, or R5F213MCQNNP equivalent, this device delivers integrated RF baseband + microcontroller functionality in a compact 40-pin HWQFN package - enabling rapid development of Zigbee/IEEE 802.15.4-compliant end devices without external RF front-end components.

Technical Context

The R5F213MCQNNP integrates an R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and 1 Mbyte address space. Its RF subsystem includes 127-byte TX/RX RAM buffers, automatic ACK response, and 26-bit timer with three compare channels for precise packet timing control.

It implements dual-clock architecture: high-speed XIN (16 MHz) for CPU/RF operation and low-frequency XCIN (32 kHz) for real-time clock and ultra-low-power wait/stop modes. Power management includes voltage detection (VDD monitoring), multiple low-power modes (wait, stop, RF off/idle), and on-chip regulators for analog/RF domains (VREGOUT1–VREGOUT4).

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R5F213MCQNNP?

The R5F213MCQNNP supports up to 16 MHz bus clock (BCLK) operation at VCC = 2.7–3.6 V. At lower frequencies - 8 MHz (VCC = 2.15–3.6 V) and 4 MHz (VCC = 1.8–3.6 V) - it maintains full functionality while enabling reduced power consumption in battery-constrained designs. The XIN clock is fixed at 16 MHz per datasheet specification.

Does the R5F213MCQNNP include hardware support for AES encryption, and what key length does it implement?

Yes, the R5F213MCQNNP includes a dedicated hardware AES engine supporting 128-bit key encryption and decryption. This enables secure MAC-layer packet processing for IEEE 802.15.4 frames without CPU overhead, ensuring deterministic timing for time-critical wireless protocols.

How many I/O pins does the R5F213MCQNNP provide, and which ones support key input interrupt functionality?

The R5F213MCQNNP provides 18 CMOS I/O ports (including XCIN/XCOUT), with eight dedicated key input interrupt pins: KI0 through KI7 mapped to P1_0–P1_7. These pins support programmable pull-up resistors and hardware debouncing, making them ideal for remote control keypad interfaces.

What RF-related peripherals are integrated into the R5F213MCQNNP, and how is antenna switching controlled?

The R5F213MCQNNP integrates a complete 2.4 GHz IEEE 802.15.4 RF transceiver with differential RFIO pins (RFIOP/RFION), on-chip regulators (VREG1–VREG4), and an antenna switch control output (ASW). The ASW pin provides a dedicated open-drain signal to drive external SPDT RF switches, simplifying T/R path management in single-antenna designs.

What low-power modes are available on the R5F213MCQNNP, and what is the minimum current draw in each?

The R5F213MCQNNP supports multiple low-power states: stop mode (2 µA), wait mode with XCIN clock (4.5–6 µA), RF off (3.5–6 mA), and RF idle (5–7.5 mA). These values are measured at VCC = VCCRF = 1.8–3.6 V with all clocks disabled except XCIN in wait mode - enabling multi-year battery life in intermittent-sensing applications.
