Product details
Overview
R5F213M8UNNP#U0 from Renesas Electronics is a 16-bit R8C/3MU Group microcontroller featuring the R8C CPU core, 64 KB flash program ROM, 8 KB RAM, and integrated USB 2.0 Full-Speed (12 Mbps) function controller with on-chip transceiver. It operates at up to 20 MHz (50 ns min instruction time), supports background operation (BGO) for 4 KB × 4 data flash blocks, and targets embedded control in USB-peripheral devices such as digital cameras and office equipment.
For engineers reviewing the R5F213M8UNNP#U0 datasheet, R5F213M8UNNP#U0 pinout, R5F213M8UNNP#U0 application, or R5F213M8UNNP#U0 equivalent, this MCU delivers verified USB device functionality, low-power wait/stop modes (4.0 µA / 2.0 µA), 30 CMOS I/O ports with pull-up selection, and hardware LIN support via Timer RA + UART0 - critical for cost-sensitive, space-constrained industrial and consumer designs.
Technical Context
The R5F213M8UNNP#U0 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte (00000h–FFFFFh), with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash at 03000h–03FFFh.
It integrates four clock sources: XIN/XOUT crystal oscillator, high-speed on-chip oscillator (frequency-adjustable), low-speed on-chip oscillator, and PLL frequency synthesizer. USB functionality includes five dedicated pipes (DCP + PIPE4–7), 448-byte FIFO (64/128/64 byte allocation), and full hardware control of D+ pull-up (USB_DPUPE), VBUS sensing (USB_VBUS), and overcurrent detection (USB_OVRCURA).

Applications
| USB Digital Camera Control | Smart Office Peripheral |
|---|---|
|
Use Scenario: Embedded controller managing image sensor interface, SD card storage, and USB mass-storage-class communication in compact digital cameras. IC Role / Device Role / Timing Role: Primary MCU executing camera firmware, driving USB bulk transfers (PIPE4/5), and coordinating timer-based exposure control.

Use Value: 30 configurable I/O ports with pull-up resistors simplify button/LED interface design; wait-mode current <4 µA extends sleep-state battery life. |
| Industrial USB Sensor Hub | Home Appliance UI Controller |
|
Use Scenario: Aggregation node collecting analog/digital sensor data (via external ADCs) and relaying it to host PC via USB CDC ACM class. IC Role / Device Role / Timing Role: USB device endpoint managing control transfers (DCP) and bulk data streaming while servicing multiple UART/I²C sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F213M6UNNP | 32 KB program ROM, 4 KB data flash, identical package and peripheral set - no USB or A/D differences since both are R8C/3MU Group. | Suitable for simpler USB peripherals with smaller firmware footprints (e.g., basic HID keyboards). | Select when firmware size <32 KB and cost sensitivity outweighs memory headroom needs. |
| R5F213M8KNNP | R8C/3MK Group variant: adds 10-channel 10-bit A/D converter and DTC; removes KI0–KI3 key inputs; same USB, clock, and memory specs. | Better for sensor-rich applications (e.g., environmental monitors) but incompatible for key-scan UIs requiring KI0–KI3. | Choose only if A/D acquisition is mandatory and key input is unused - not a drop-in replacement due to pin function reassignment. |
Compared with R5F213M8UNNP#U0, R5F213M6UNNP offers lower memory capacity at reduced cost for less complex USB devices, while R5F213M8KNNP trades key-input capability for analog sensing - making R5F213M8UNNP#U0 the optimal choice for keyboard-centric or button-driven USB peripherals needing maximum firmware headroom.

FAQ
What USB speed and device class does R5F213M8UNNP#U0 support?
R5F213M8UNNP#U0 supports USB 2.0 Full-Speed (12 Mbps) as a device-only controller. It implements standard USB device classes including CDC ACM (virtual COM port), HID (keyboard/mouse), and MSC (mass storage) via firmware - no host or OTG capability. The on-chip transceiver and 448-byte FIFO enable reliable enumeration and data transfer without external PHY components.
Does R5F213M8UNNP#U0 include an analog-to-digital converter (ADC)?
No, R5F213M8UNNP#U0 does not include an ADC. It belongs to the R8C/3MU Group, which explicitly omits A/D converter functionality per datasheet Table 1.1. Pins P0_0–P0_7 and P1_0–P1_3 are designated for timer/trace/key functions only - not analog input. For ADC requirements, consider the R8C/3MK Group part R5F213M8KNNP instead.
What are the power supply requirements for R5F213M8UNNP#U0?
R5F213M8UNNP#U0 operates from 1.8 V to 5.5 V across −20°C to +85°C. It features a built-in voltage detection circuit with programmable reset thresholds and supports three low-power modes: standard (7.0 mA @ 5 V/20 MHz), wait (4.0 µA @ 3 V), and stop (2.0 µA @ 3 V). AVCC/AVSS pins are present but unused - no analog supply is required.
How is the USB D+ pull-up resistor controlled on R5F213M8UNNP#U0?
R5F213M8UNNP#U0 controls the USB D+ pull-up via the dedicated output pin USB_DPUPE. This signal drives an internal 1.5 kΩ pull-up resistor to VDD when asserted - enabling hardware-managed USB reset and enumeration without software timing dependency. The pin is active-high and must be driven by firmware during USB initialization sequences.
Is R5F213M8UNNP#U0 pin-compatible with other R8C/3MU or R8C/3MK devices?
R5F213M8UNNP#U0 shares the PWQN0040KB-B 40-pin QFN package and identical pinout with all R8C/3MU Group variants (e.g., R5F213M6UNNP) and R8C/3MK Group parts (e.g., R5F213M8KNNP). However, pin functions differ: R8C/3MK adds AN0–AN11 and ADTRG but removes KI0–KI3 key inputs. Thus, R5F213M8UNNP#U0 is pin-compatible but not function-compatible with R8C/3MK devices.
