Product details
Overview
R5F1036AASM#75 from Renesas is a 20-pin RL78/G12 16-bit microcontroller with 16 KB code flash, 1 KB RAM, and no data flash memory, operating at 1.8–5.5 V across –40°C to +85°C for consumer applications. It features a 24 MHz high-speed on-chip oscillator (±5% accuracy), 10-bit 11-channel ADC, 4-channel 16-bit timer, UART, CSI, and ultra-low-power HALT/STOP/SNOOZE modes - deployed in battery-powered sensor nodes and smart home control units.
For engineers reviewing the R5F1036AASM#75 datasheet, R5F1036AASM#75 pinout, R5F1036AASM#75 application, or R5F1036AASM#75 equivalent, key selection criteria include its TSSOP-20 package, absence of DMA and data flash, ±5% oscillator tolerance over industrial temperature range, and compatibility with RL78 toolchains and IAR/CS+ IDEs.
Technical Context
The R5F1036AASM#75 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting minimum instruction execution time of 0.04167 µs at 24 MHz. 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 for sub-63 μA/MHz operation.
Peripheral integration includes one UART channel, one simplified SPI (CSI) channel, no simplified I²C, 11-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and four 16-bit timer channels with PWM capability. It lacks DMA, CRC, RAM guard, and SFR guard functions present in R5F102 variants.

FAQ
What is the maximum operating frequency and instruction throughput of the R5F1036AASM#75?
The R5F1036AASM#75 operates at up to 24 MHz using its high-speed on-chip oscillator, achieving 31 DMIPS performance. Its RL78 CPU core executes instructions in a 3-stage pipeline with minimum instruction time of 0.04167 µs at 24 MHz. The device supports HS mode (1–24 MHz) and LS mode (1–8 MHz), with actual frequency dependent on VDD and temperature conditions specified in the datasheet.
Does the R5F1036AASM#75 support in-system programming and debug interfaces?
Yes, the R5F1036AASM#75 includes an on-chip debug function compatible with Renesas E2 emulator and standard SWD protocols. It supports flash self-programming via the Flash Self Programming Library Type01, though this requires careful RAM allocation and code flash partitioning. Debug access uses dedicated TOOL0, TOOLRxD, and TOOLTxD pins mapped to P40, P11, and P12 respectively.
What are the analog capabilities of the R5F1036AASM#75, and how is the ADC calibrated?
The R5F1036AASM#75 integrates an 11-channel, 10-bit successive-approximation ADC with internal 1.45 V reference voltage and on-die temperature sensor. It supports single-ended and differential input modes, sample-and-hold, and automatic scanning. No factory calibration is performed; users must apply software offset/gain correction using known reference voltages - the datasheet provides typical INL/DNL specs but no trim registers.
Can the R5F1036AASM#75 drive standard 5 V logic directly from its I/O pins?
No, the R5F1036AASM#75 I/O pins are not 5 V tolerant except for two dedicated N-ch open-drain outputs (P60 and P61), rated to 6 V. All other GPIOs operate at VDD level (1.8–5.5 V) and must not exceed VDD + 0.3 V. To interface with 5 V systems, level-shifting circuitry or external buffer ICs are required unless VDD is set to 5 V and signals remain within safe margins.
How does the power management of the R5F1036AASM#75 compare to the R5F1026AASM#75?
The R5F1036AASM#75 maintains identical ultra-low-power HALT, STOP, and SNOOZE modes as the R5F1026AASM#75, with 63 μA/MHz active current. However, it lacks the R5F1026AASM#75's RAM guard and SFR guard features, reducing protection against unintended memory corruption during low-power transitions. Both share the same POR, LVD, and watchdog reset mechanisms.
