Overview
R5F213M8KNNP from Renesas is a 16-bit R8C/3MK Group microcontroller featuring 64 KB flash ROM, 8 KB RAM, and integrated USB 2.0 full-speed device controller with 448-byte FIFO, 10-bit A/D converter (10 channels), and DTC with 26 activation sources. It operates at up to 20 MHz (5.5 V) and supports −20°C to +85°C ambient temperature in industrial control and embedded USB peripheral applications.
For engineers reviewing the R5F213M8KNNP datasheet, R5F213M8KNNP pinout, R5F213M8KNNP application, or R5F213M8KNNP equivalent, key selection criteria include USB device controller integration, on-chip A/D conversion capability, DTC support for efficient data transfers, low-power operating modes (wait/stop), and QFN-40 package compatibility with space-constrained PCB layouts.
Technical Context
The R5F213M8KNNP implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte, with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash (4 × 1 KB blocks) mapped at 03000h–03FFFh.
Peripheral integration includes three UARTs (UART0/1/3), one UART2 with multiprocessor mode, I²C/SSU shared interface, LIN module (using Timer RA and UART0), watchdog timer (14-bit), and voltage detection circuit with selectable levels. The USB function controller supports control, bulk, and interrupt transfers across five pipes with programmable endpoint assignment.

FAQ
What USB device classes does the R5F213M8KNNP support natively?
The R5F213M8KNNP supports USB device classes requiring control, bulk, and interrupt transfers-including CDC (communication device class), HID (human interface device), MSC (mass storage class), and DFU (device firmware upgrade). Its 5-pipe architecture with configurable endpoints enables simultaneous implementation of multiple class interfaces, and the on-chip transceiver eliminates external PHY requirements. All USB functionality is managed by the integrated USB function controller in the R5F213M8KNNP.
Does the R5F213M8KNNP support USB host functionality?
No, the R5F213M8KNNP implements only USB device controller functionality compliant with USB 2.0 full-speed specification. It lacks USB host controller logic, OTG support, or VBUS powering capability required for host operation. The R5F213M8KNNP is designed exclusively for peripheral roles such as USB audio devices, HID controllers, or firmware update targets-not for enumerating other USB peripherals.
How is the A/D converter triggered in the R5F213M8KNNP?
The R5F213M8KNNP A/D converter supports software start, internal timer triggers (e.g., Timer RC output compare), and external hardware trigger via the ADTRG pin (Pin 24). This allows precise synchronization with system events like PWM edges or sensor excitation pulses. Conversion results are accessible via dedicated SFRs, and the 10-bit result can be read in single or sweep mode across all 10 channels. The A/D function is fully integrated into the R5F213M8KNNP's peripheral set without external components.
What low-power modes are available on the R5F213M8KNNP and how do they differ?
The R5F213M8KNNP provides standard operating mode, wait mode (CPU halted, peripherals active, 4.0 µA @ 3.0 V), and stop mode (all clocks stopped except low-speed oscillator, 2.0 µA @ 3.0 V). Wake-up sources include external interrupts, key inputs, A/D completion, and USB resume. These modes are controlled via system clock registers and are implemented in silicon within the R5F213M8KNNP-no external circuitry is needed to achieve sub-µA standby operation.
Is the R5F213M8KNNP pin-compatible with other R8C/3M series MCUs?
Yes, the R5F213M8KNNP shares the PWQN0040KB-B (40-pin QFN) package and identical pinout with R5F213M8UNNP, R5F213M6UNNP, and R5F213MCKNNP. Signal assignments-including USB_DP/DM, A/D inputs (AN0–AN11), and I/O port mappings-are consistent across these variants. This allows hardware reuse across different memory configurations and feature sets, simplifying design scalability for the R5F213M8KNNP and its family members.
