Product details
Overview
R5F213J4TNNP from Renesas is an 8-bit R8C CPU core MCU with 16 KB flash ROM, 1.5 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). It operates at up to 20 MHz (VCC = 2.7–5.5 V), features a 16×16→32-bit hardware multiplier, 10-bit ×12-channel ADC, and integrated LIN module for automotive body electronics control.
For engineers reviewing the R5F213J4TNNP datasheet, R5F213J4TNNP pinout, R5F213J4TNNP application, or R5F213J4TNNP equivalent, key selection criteria include its 40-pin HXQFN package, −20°C to +85°C industrial temperature grade, low-power wait/stop modes (3.5 µA / 2.0 µA), and dual UART + I²C + LIN interface integration for appliance and sensor control systems.
Technical Context
The R5F213J4TNNP implements the R8C CPU core with 89 fundamental instructions and supports single-chip mode across a 1 Mbyte address space. Its memory architecture includes dedicated SFR regions (00000h–002FFh, 02C00h–02FFFh), fixed interrupt vector table (0FFDCh–0FFFFh), and segmented flash layout (program ROM at 08000h–0BFFFh, data flash at 03000h–03FFFh).
Peripheral subsystems are tightly coupled via dedicated SFRs: Timer RC uses TRCMR (0120h) and TRCCR1 (0121h) for capture/compare/PWM; UART2 leverages U2MR (00A8h), U2C0 (00ACh), and U2SMR (00BFh); LIN functionality shares Timer RA and UART0 resources with LINCR (0106h) and LINST (0107h) registers.
Key Specifications

FAQ
What is the maximum operating frequency and supply voltage range for the R5F213J4TNNP?
The R5F213J4TNNP operates at up to 20 MHz when supplied with 2.7 V to 5.5 V. At lower voltages (1.8 V to 5.5 V), the maximum frequency is reduced to 5 MHz to maintain timing margins. This dual-voltage/frequency capability allows flexible power optimization in battery-powered and line-powered designs without changing the R5F213J4TNNP part number.
Does the R5F213J4TNNP support in-application programming (IAP) of its data flash memory?
Yes, the R5F213J4TNNP supports background operation (BGO) for data flash, enabling R5F213J4TNNP firmware to erase and reprogram 1 KB data flash blocks while continuing normal program execution. This capability is essential for logging sensor data or storing calibration parameters without system interruption.
How many analog-to-digital converter (ADC) channels does the R5F213J4TNNP provide, and what is their resolution?
The R5F213J4TNNP integrates a 10-bit successive-approximation ADC with 12 input channels (AN0–AN11), including sample-and-hold functionality and sweep mode for automatic channel sequencing. This ADC configuration supports simultaneous monitoring of multiple analog sensors-such as temperature, light, and position-in a single R5F213J4TNNP device.
What peripheral interfaces are available on the R5F213J4TNNP for communication with external devices?
The R5F213J4TNNP provides UART0, UART2 (with I²C, SPI, and SSU modes), and a hardware LIN module. UART2's I²C mode supports standard 100 kHz/400 kHz bus speeds, while the LIN module complies with ISO 9141-2 and SAE J2602, allowing direct connection to automotive LIN networks without external transceivers.
Is the R5F213J4TNNP pin-compatible with other members of the R8C/3JT Group, such as R5F213J5TNNP or R5F213J6TNNP?
Yes, the R5F213J4TNNP shares identical 40-pin HXQFN packaging (PXQN0040LA-A), pin assignments, and peripheral register mapping with R5F213J5TNNP and R5F213J6TNNP. This pin-to-pin compatibility allows direct substitution during prototyping or production ramp-up when increased memory capacity is required-no PCB layout change is needed for migration between these R8C/3JT Group variants.
