Renesas R5F12007GNS#50

Overview

R5F12007GNS#50 from Renesas Electronics is an RL78/G15 8-bit microcontroller with 4 KB code flash, 1 KB RAM, and 1 KB data flash, operating from 2.4 V to 5.5 V. It features an RL78 CPU core (3-stage pipeline), 8-channel 16-bit timer, 3-channel 8/10-bit ADC, single simplified SPI (CSI), UART, and simplified I²C - deployed in industrial temperature-grade (−40°C to +105°C) applications such as sensor interface modules and low-power control units.

For engineers reviewing the R5F12007GNS#50 datasheet, R5F12007GNS#50 pinout, R5F12007GNS#50 application, or R5F12007GNS#50 equivalent, key selection criteria include its 8-pin LSSOP package, 4 KB flash capacity, industrial-temperature operation, integrated on-chip debug, and support for HALT/STOP low-power modes - all critical for space-constrained embedded control designs requiring long-term supply stability and functional safety margins.

Technical Context

The R5F12007GNS#50 implements the RL78-S2 CPU core with CISC architecture, supporting instruction execution times from 0.0625 μs (at 16 MHz high-speed on-chip oscillator) to 1.0 μs (at 1 MHz). Its clock system integrates a selectable high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy at −20°C to +85°C), low-speed 15 kHz on-chip oscillator, and external crystal input (X1/X2, 1–12 MHz).

Peripherals include a 3-channel 8/10-bit A/D converter with internal reference (0.815 V), one comparator (IVCMP0), programmable clock/buzzer output (PCLBUZ0), and interrupt controller supporting up to six external interrupt sources (INTP0–INTP5). The device uses a single 8-bit port (Port 0) plus dedicated pins (P40, P125, P137) for debug, reset, and timer functions.

FAQ

What is the maximum operating frequency of the R5F12007GNS#50?

The R5F12007GNS#50 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, enabling a minimum instruction execution time of 0.0625 μs. External crystal operation is also supported up to 12 MHz via X1/X2 pins. Frequency accuracy is ±1.0% over −20°C to +85°C for industrial-grade G-suffix devices.

Does the R5F12007GNS#50 support in-system programming?

Yes, the R5F12007GNS#50 supports self-programming of both code flash and data flash memory without requiring a boot swap function. Programming is performed via the on-chip debug interface (TOOL0/TOOLRxD/TOOLTxD) using standard Renesas flash programming algorithms - enabling field firmware updates and calibration data storage.

How many analog input channels does the R5F12007GNS#50 have?

The R5F12007GNS#50 integrates an 8/10-bit A/D converter with three dedicated analog input channels: ANI0, ANI2, and ANI3. These correspond to physical pins P01, P03, and P04 respectively. Internal reference voltage (0.815 V) is available for ratiometric measurements, and conversion is controlled entirely by on-chip peripheral registers.

What communication interfaces are available on the R5F12007GNS#50?

The R5F12007GNS#50 provides one UART channel (RxD0/TxD0), one simplified SPI (CSI00) channel, and one simplified I²C (IIC00) channel - all multiplexed on Port 0 pins. No full I²C bus master/slave or standard SPI with dedicated MOSI/MISO is implemented; CSI and simplified I²C use shared clock/data lines with reduced protocol overhead.

Is the R5F12007GNS#50 pin-compatible with other RL78/G15 variants?

No - the R5F12007GNS#50 uses an 8-pin LSSOP package with a fixed pinout defined for 8-pin products. It is not pin-compatible with 10-, 16-, or 20-pin RL78/G15 variants (e.g., R5F12017GSP#50 or R5F12047GSP#50), which have different pin counts, functions per pin, and physical dimensions. Migration requires PCB layout revision.
