Renesas R5F102AAGSP#10

Overview

R5F102AAGSP#10 from Renesas Electronics is a 30-pin LSSOP-packaged RL78/G12 16-bit MCU with 16 KB code flash, 2 KB data flash, and 2 KB RAM, operating at 1.8–5.5 V and delivering 31 DMIPS at 24 MHz. It integrates an ultra-low-power architecture (63 μA/MHz), 8-channel 16-bit TAU timer, 8-channel 10-bit A/D converter, UART/CSI/I²C serial interfaces, DMA controller, and CRC hardware - deployed in battery-powered industrial sensors and smart metering endpoints.

For engineers reviewing the R5F102AAGSP#10 datasheet, R5F102AAGSP#10 pinout, R5F102AAGSP#10 application, or R5F102AAGSP#10 equivalent, key selection criteria include its G-grade (−40°C to +105°C) industrial temperature rating, on-chip data flash for firmware parameter storage, high-accuracy ±1.0% on-chip oscillator (−20°C to +85°C), and hardware safety features including RAM/SFR guard and CRC operation.

Technical Context

The R5F102AAGSP#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture and 1 MB address space, supporting instruction execution times from 0.04167 µs (24 MHz on-chip oscillator) to 1 µs (1 MHz). Its clock system combines a high-speed on-chip oscillator (1–24 MHz, ±1.0% accuracy), low-speed 15 kHz on-chip oscillator, and external crystal support (1–20 MHz).

Peripheral integration includes two SAU channels (supporting UART, CSI, I²C), 8-channel TAU0 timer with PWM capability, 12-bit interval timer, window watchdog timer, and programmable clock/buzzer output (2.44 kHz–10 MHz). The device supports background data flash rewriting (BGO) and self-programming with flash shield window protection.

FAQ

What is the maximum operating frequency and corresponding DMIPS performance of the R5F102AAGSP#10?

The R5F102AAGSP#10 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This is confirmed in the official Renesas datasheet R01DS0193EJ0250 Rev.2.50, which specifies the RL78/G12 family's performance at 24 MHz. The R5F102AAGSP#10 maintains this performance across its full 1.8–5.5 V supply range and −40°C to +105°C industrial temperature grade.

Does the R5F102AAGSP#10 include on-chip data flash memory, and what is its endurance specification?

Yes, the R5F102AAGSP#10 includes 2 KB of on-chip data flash memory, supporting background operation (BGO) and rated for 1,000,000 write/erase cycles (typical). This capability is explicitly documented in the RL78/G12 datasheet section 1.1 Features and Table 1-1, distinguishing R5F102x products from R5F103x variants that omit data flash entirely.

What safety features are implemented in the R5F102AAGSP#10, and how are they utilized in industrial designs?

The R5F102AAGSP#10 integrates CRC calculation hardware, RAM guard, and SFR guard - all confirmed in datasheet sections 1.3.3 and 1.6.3. In industrial designs, these features enable runtime memory integrity checks: CRC verifies firmware/data blocks, RAM guard detects unintended writes to protected regions, and SFR guard prevents accidental modification of critical peripheral registers - collectively enhancing functional safety compliance.

How many analog input channels does the R5F102AAGSP#10 support, and what is the ADC resolution?

The R5F102AAGSP#10 supports 8 analog input channels with 10-bit resolution, as specified for 30-pin RL78/G12 devices in datasheet section 1.7 Outline of Functions. It includes internal 1.45 V reference voltage and an integrated temperature sensor, enabling accurate sensor signal acquisition without external references in applications like environmental monitoring and motor control.

What package type and pin count does the R5F102AAGSP#10 use, and is it RoHS-compliant?

The R5F102AAGSP#10 uses a 30-pin plastic LSSOP package (7.62 mm, 0.65-mm pitch), identified by the "SP" suffix and "#10" tray packaging code per Figure 1-1 and Table 1-1 in the datasheet. It is RoHS-compliant and qualified for industrial temperature operation (−40°C to +105°C), with explicit mechanical dimensions and land pattern guidance provided in Renesas' PLSP0030JB-B package drawing.
