Renesas R5F12007MNS#10

Overview

R5F12007MNS#10 from Renesas Electronics is a 16 MHz 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 across −40°C to +125°C industrial temperature range. It integrates an 8/10-bit 4-channel ADC, 8-channel 16-bit timer array, UART, simplified SPI (CSI), and simplified I²C interfaces - deployed in motor control subsystems for HVAC actuators and smart power outlets.

For engineers reviewing the R5F12007MNS#10 datasheet, R5F12007MNS#10 pinout, R5F12007MNS#10 application, or R5F12007MNS#10 equivalent, key selection criteria include its 10-pin LSSOP package, M-grade thermal rating, 4 KB flash capacity, on-chip debug support, and integrated comparator with internal reference voltage.

Technical Context

The R5F12007MNS#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.0625 μs at 16 MHz using the high-speed on-chip oscillator. Its memory map spans 1 MB address space with four banks of 8-bit general-purpose registers.

Power management includes HALT and STOP low-power modes, selectable power-on-reset (SPOR) with four voltage thresholds, and dual on-chip oscillators: high-speed (1–16 MHz, ±1.0% accuracy at −20°C to +85°C) and low-speed (15 kHz). Peripheral I/O redirection enables flexible pin function assignment via PIOR registers.

FAQ

What is the maximum operating frequency and oscillator accuracy of the R5F12007MNS#10?

The R5F12007MNS#10 supports a maximum high-speed on-chip oscillator frequency of 16 MHz with ±1.0% accuracy over −20°C to +85°C and ±1.5% over −40°C to −20°C or +85°C to +125°C. External crystal operation up to 12 MHz is also supported via X1/X2 pins. This accuracy enables reliable UART communication at 115.2 kbps without external trimming components.

How many analog input channels does the R5F12007MNS#10 support, and what reference options are available?

The R5F12007MNS#10 supports 4 analog input channels (ANI0–ANI3) with 8/10-bit resolution. It provides internal reference voltage (0.815 V TYP.) on IVREF0 for comparator use and allows external reference input on IVREF0/IVREF1. The ADC operates across the full 2.4–5.5 V supply range, enabling direct measurement of unregulated battery voltages or sensor outputs.

Does the R5F12007MNS#10 support in-system programming of its flash memory?

Yes, the R5F12007MNS#10 supports self-programming of both code flash and data flash memory without boot swap functionality. Code flash writes require block erase (1 KB) before programming, while data flash supports 32-bit unit rewrites up to 1,000,000 times. Background operation is not supported - CPU execution halts during data flash writes.

What serial communication interfaces are integrated into the R5F12007MNS#10?

The R5F12007MNS#10 integrates one UART channel, two simplified SPI (CSI) channels, and two simplified I²C channels. It does not include full I²C bus master/slave compliance but supports basic addressable serial peripheral communication. All interfaces share multiplexed pins with GPIO and timer functions, configurable via peripheral I/O redirection registers (PIOR).

What is the package type and pin count of the R5F12007MNS#10?

The R5F12007MNS#10 uses a 10-pin plastic LSSOP package (4.4 × 3.6 mm, 0.65-mm pitch) with lead-free and RoHS-compliant construction. Pin functions include VDD, VSS, RESET̅, TOOL0/TOOLRxD/TOOLTxD, four analog inputs (ANI0–ANI3), and six general-purpose I/O lines with timer, serial, and interrupt capabilities.
