Product details
Overview
R5F1036AASM#15 from Renesas Electronics is a 20-pin TSSOP-packaged RL78/G12 16-bit microcontroller designed for ultra-low-power general-purpose embedded control. It features 16 KB code flash, 1 KB RAM, 10-bit 11-channel A/D converter, 4-channel 16-bit timer, UART, simplified SPI (CSI), and operates from 1.8 V to 5.5 V with 63 μA/MHz active current - enabling battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F1036AASM#15 datasheet, R5F1036AASM#15 pinout, R5F1036AASM#15 application, or R5F1036AASM#15 equivalent, key selection criteria include its 20-pin TSSOP package, absence of data flash memory, single UART channel, lack of DMA and safety functions (CRC/RAM guard), and ±5.0% high-speed on-chip oscillator accuracy over –40°C to +85°C.
Technical Context
The R5F1036AASM#15 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting 1 MB address space and 8-bit register banks. Its clock system integrates a high-speed on-chip oscillator (selectable 1–24 MHz) and low-speed 15 kHz on-chip oscillator, with power management including HALT, STOP, and SNOOZE modes.
Peripheral integration includes one UART channel, one simplified SPI (CSI) channel, no simplified I²C, 11-channel 10-bit A/D converter with internal reference (1.45 V) and temperature sensor, and four 16-bit timer channels - all mapped to 18 I/O pins in the 20-pin TSSOP footprint, with two 6-V-tolerant N-ch open-drain outputs.

FAQ
What is the maximum operating frequency of the R5F1036AASM#15?
The R5F1036AASM#15 supports a maximum high-speed on-chip oscillator frequency of 24 MHz, delivering 31 DMIPS performance. When using an external crystal (X1/X2), the maximum main system clock frequency is 20 MHz at VDD ≥ 2.7 V or 16 MHz at VDD ≥ 2.4 V. The instruction execution time ranges from 0.04167 µs (24 MHz on-chip) to 0.05 µs (20 MHz external).
Does the R5F1036AASM#15 include data flash memory?
No, the R5F1036AASM#15 does not include data flash memory. As confirmed in the RL78/G12 datasheet Section 1.3.1, R5F103 products (including R5F1036AASM#15) have no mounted data flash, unlike R5F102 variants which provide 2 KB. This omission reduces cost and power but requires external non-volatile storage for parameter retention.
What are the key differences between R5F1036AASM#15 and R5F1026AASM#15?
The R5F1036AASM#15 lacks data flash memory, DMA controller, CRC operation, RAM guard, and SFR guard - features present in the R5F1026AASM#15. Its high-speed on-chip oscillator accuracy is ±5.0% (vs. ±1.0% for R5F1026AASM#15), and it omits simplified I²C support. Both share identical 20-pin TSSOP packaging and core peripherals like UART and CSI.
Which development tools support the R5F1036AASM#15?
The R5F1036AASM#15 is supported by Renesas' CS+ IDE, e2 studio, and IAR Embedded Workbench for RL78. Hardware debugging uses E2 emulator Lite or E2 emulator, both compatible with the on-chip debug interface. The R5F1036AASM#15 pinout matches the RL78/G12 starter kit SK-RG12-001 for rapid prototyping.
Can the R5F1036AASM#15 operate from a single 1.8 V supply?
Yes, the R5F1036AASM#15 operates across 1.8 V to 5.5 V, enabling direct use with 1.8 V logic families and single-cell lithium batteries. At 1.8 V, the maximum high-speed on-chip oscillator frequency is 8 MHz (LS mode), and the A/D converter maintains full 10-bit resolution with internal 1.45 V reference - verified per RL78/G12 datasheet Section 2.3 DC Characteristics.
