Product details
Overview
R5F11EAAASP#70 from Renesas is an ultra-low-power 16-bit RL78/G1G microcontroller in a 30-pin LSSOP package, featuring 16 KB flash memory, 1.5 KB RAM, 26 I/O pins, 8-channel 10-bit A/D converter, and dual UART interfaces - deployed in battery-powered sensor nodes and industrial control panels requiring extended runtime and compact footprint.
For engineers reviewing the R5F11EAAASP#70 datasheet, R5F11EAAASP#70 pinout, R5F11EAAASP#70 application, or R5F11EAAASP#70 equivalent, key selection criteria include its 30-pin LSSOP (0.65 mm pitch) package, HALT/STOP/SNOOZE low-power modes, on-chip high-speed oscillator accuracy of ±2.0%, and support for self-programming with flash shield window function.
Technical Context
The R5F11EAAASP#70 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and multiply/divide/accumulate instructions. It integrates a 12-bit interval timer, watchdog timer, event link controller (18 input events), and programmable gain amplifier (PGAI) tied to P01.
Its peripheral set includes one simplified SPI (CSI), two UARTs (UART0 and UART1), one simplified I²C interface, seven 16-bit timers (TAU:4, Timer RJ:1, Timer RD:2), and two comparators with DAC-based reference voltage selection - all configurable via peripheral I/O redirection register 1 (PIOR1 = 00H).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response in motor control and sensor polling loops. |
| Flash / RAM | 16 KB code flash (1 KB block size) + 1.5 KB SRAM; supports secure block erase prohibition and self-programming with flash shield window. |
| Operating Voltage | 2.7 V to 5.5 V single supply; allows direct integration with 3.3 V or 5 V system rails without level-shifting. |

| Low-Power Modes | HALT, STOP, SNOOZE; STOP mode draws typical 0.23 µA at VDD = 3.0 V, enabling multi-year battery life in IoT endpoints. |
| Oscillator Options | High-speed on-chip oscillator (1–24 MHz, ±2% accuracy) + external crystal (1–20 MHz); eliminates need for external clock source in cost-sensitive designs. |
| I/O Count | 26 total I/O pins (23 CMOS I/O + 3 CMOS input); includes N-ch open-drain, TTL input buffer, and on-chip pull-up resistor per pin. |
Pinout & Package
Package: 30-pin plastic LSSOP (7.62 mm, 0.65 mm pitch), RoHS-compliant, tape-and-reel (#70 suffix). Requires 0.47–1 µF capacitor between REGC and 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 for A/D conversion. |
| P21/ANI1/AVREFM | Analog input / A/D reference (−) | Analog channel 1 input; doubles as negative reference for differential A/D measurements. |

| P30/INTP3/SCK00/SCL00/TRJO0 | Serial clock / I²C clock | Provides clock for SPI and I²C peripherals; also functions as trace port output for on-chip debug. |
| P00/ANI17/TI00/TxD1/CMP0P/(TRJO0) | Analog input / UART1 transmit / comparator input | Enables simultaneous analog sensing (ANI17), serial communication (TxD1), and analog comparison (CMP0P). |
| P137/INTP0 | External interrupt 0 input | Dedicated edge-triggered interrupt pin for wake-up from STOP mode or real-time event capture. |
| RESET | Active-low reset input | Accepts external reset signal; internally driven by POR, LVD, watchdog timeout, illegal instruction, or RAM parity error. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power STOP mode | 0.23 µA typical current draw at 3.0 V enables decade-scale battery operation in remote sensors. |
| On-chip high-speed oscillator | ±2.0% accuracy across -40°C to +85°C eliminates external crystal for timing-critical but non-precision applications. |
| Event Link Controller (ELC) | Direct hardware linking of 18 event sources (e.g., timer overflow, ADC end-of-conversion) to peripheral triggers avoids CPU overhead. |
| Self-programmable flash | Flash shield window function prevents unauthorized rewriting while permitting field firmware updates via user program. |
| Dual UART + simplified I²C + CSI | Three independent serial interfaces enable concurrent communication with BLE modules, displays, and sensors without external bridging logic. |

FAQ
What is the maximum operating frequency of the R5F11EAAASP#70?
The R5F11EAAASP#70 supports a maximum high-speed on-chip oscillator frequency of 24 MHz and an external crystal clock up to 20 MHz. In HS (high-speed main) mode, the CPU executes instructions at minimum 0.04167 µs per cycle (24 MHz), enabling real-time response in motor control and sensor fusion applications. The actual system clock is configurable via the HOCODIV register and option byte settings.
Does the R5F11EAAASP#70 support in-system programming?
Yes, the R5F11EAAASP#70 supports self-programming of its 16 KB flash memory using the on-chip debug interface or user firmware. It includes a flash shield window function to prevent unauthorized rewriting of protected sectors, and the RL78 Family Flash Self-Programming Library Type01 must be used for safe field updates. Programming requires VDD ≥ 2.7 V and adherence to timing specifications in the user's manual.
What are the key differences between R5F11EAAASP#70 and R5F11EA8ASP#70?
The R5F11EAAASP#70 and R5F11EA8ASP#70 share identical 30-pin LSSOP packaging, pinout, RAM (1.5 KB), peripherals, and low-power features. Their sole functional difference is flash memory size: R5F11EAAASP#70 has 16 KB, while R5F11EA8ASP#70 has 8 KB. Both support the same instruction set, oscillator options, and debug capabilities - making R5F11EA8ASP#70 a direct cost-optimized alternative when firmware fits within 8 KB.
Can the R5F11EAAASP#70 operate from a 3.3 V supply?
Yes, the R5F11EAAASP#70 operates reliably across 2.7 V to 5.5 V, including standard 3.3 V supply rails. Its I/O pins support TTL input buffers (VIH ≥ 2.0 V at 3.3 V) and CMOS levels, and analog peripherals like the 10-bit A/D converter maintain full specification over this range. The on-chip voltage detector (LVD) can be configured to generate interrupts or resets at six selectable thresholds between 2.75 V and 4.06 V.
How many serial interfaces does the R5F11EAAASP#70 integrate?
The R5F11EAAASP#70 integrates three serial interfaces: one simplified SPI (called CSI in Renesas documentation), two UART channels (UART0 and UART1), and one simplified I²C interface. UART0 uses P50 (RxD0) and P51 (TxD0); UART1 uses P01 (RxD1) and P00 (TxD1); I²C uses P30 (SCL00) and P50 (SDA00). All are independently configurable and support simultaneous operation without resource conflict.
