Product details
Overview
R5F11EAAASP#50 from Renesas is a 30-pin, 16 KB flash, 1.5 KB RAM RL78/G1G 16-bit microcontroller with ultra-low power consumption (HALT/STOP/SNOOZE modes), 24 MHz high-speed on-chip oscillator (±2% accuracy), 8-channel 10-bit A/D converter, two comparators, and integrated programmable gain amplifier. It operates from 2.7–5.5 V across –40°C to +85°C and targets battery-powered sensor nodes and appliance control panels.
For engineers reviewing the R5F11EAAASP#50 datasheet, R5F11EAAASP#50 pinout, R5F11EAAASP#50 application, or R5F11EAAASP#50 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative parts - all grounded in Renesas' official R01DS0241EJ0150 Rev. 1.50 documentation.
Technical Context
The R5F11EAAASP#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and support for multiply/divide/accumulate instructions. Its memory map spans 1 MB address space, with 16 KB code flash (1 KB block size) and 1.5 KB on-chip RAM - including 630 bytes reserved for self-programming operations.
It integrates dual serial interfaces (UART0 + UART1), simplified SPI (CSI), simplified I²C, seven 16-bit timers (TAU, Timer RJ, Timer RD), a 12-bit interval timer, watchdog timer, and event link controller (ELC) supporting 18 event inputs and 6 trigger outputs for deterministic peripheral coordination.

Pinout & Package
30-pin plastic LSSOP (7.62 mm, 0.65 mm pitch) package with REGC capacitor connection requirement (0.47–1 µF to VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P20/ANI0/AVREFP | Analog input / A/D reference (+) | Primary analog channel 0 input; also serves as positive reference voltage source for A/D conversion. |
| P21/ANI1/AVREFM | Analog input / A/D reference (–) | Analog channel 1 input; also provides negative reference potential for A/D converter. |

FAQ
What is the maximum operating frequency of the R5F11EAAASP#50?
The R5F11EAAASP#50 supports a maximum high-speed on-chip oscillator frequency of 24 MHz (±2% accuracy) and a maximum external crystal oscillator frequency of 20 MHz. Instruction execution time reaches 0.04167 µs at 24 MHz operation, enabling responsive real-time control in applications such as motor commutation or sensor fusion. The device also supports low-speed modes down to 1 MHz for ultra-low power operation.
Does the R5F11EAAASP#50 support in-system programming?
Yes, the R5F11EAAASP#50 supports in-system programming via its on-chip debug interface and self-programming flash capability. It includes a flash shield window function that allows selective protection of memory regions during firmware updates. The R5F11EAAASP#50 uses the RL78 family Flash Self-Programming Library Type01, which reserves 630 bytes of RAM and corresponding flash sectors for safe reprogramming without external programmers.
How many analog input channels does the R5F11EAAASP#50 provide?
The R5F11EAAASP#50 provides eight analog input channels: ANI0 through ANI3 (on P20–P23) and ANI16 through ANI19 (on P01, P00, P147, and P120). All channels support 10-bit A/D conversion with selectable reference voltages (VDD, internal 1.45 V, or AVREFP/AVREFM). The internal temperature sensor is accessible via ANI16, enabling ambient temperature compensation without external components.
What power-saving modes are available on the R5F11EAAASP#50?
The R5F11EAAASP#50 offers HALT, STOP, and SNOOZE low-power modes. HALT mode draws 0.52 µA typical current while retaining RAM and register contents; STOP mode reduces current to 0.37 µA with full register retention; SNOOZE mode enables fast wake-up (≤3.5 µs) from UART, ADC, or timer events. These modes are controlled via system control registers and supported by the on-chip voltage detector and power-on-reset circuit.
Is the R5F11EAAASP#50 pin-compatible with other RL78/G1G variants?
The R5F11EAAASP#50 is pin-compatible only with other 30-pin LSSOP variants in the RL78/G1G family, specifically R5F11EA8ASP#50. It is not pin-compatible with 32-pin (e.g., R5F11EBAAFP#50) or 44-pin (e.g., R5F11EFAAFP#50) members due to differing pin counts, pitch, and peripheral mappings. Pin compatibility is confirmed by identical pin configuration diagrams and shared port assignments in the R01DS0241EJ0150 datasheet.
