Product details
Overview
R5F11EAAASP#30 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, and dual UART + simplified SPI + simplified I²C interfaces - deployed in battery-powered sensor nodes and home appliance control panels.
For engineers reviewing the R5F11EAAASP#30 datasheet, R5F11EAAASP#30 pinout, R5F11EAAASP#30 application, or R5F11EAAASP#30 equivalent, key selection criteria include its LSSOP-30 package, -40°C to +85°C industrial temperature range, 2.7–5.5 V single-supply operation, and integrated event link controller (ELC) for deterministic peripheral triggering without CPU intervention.
Technical Context
The R5F11EAAASP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and support for multiply/divide/MAC instructions. Its memory map spans 1 MB address space, with code flash organized in 1 KB blocks supporting self-programming and security-based block erase prohibition.
Peripherals are tightly coupled via the Event Link Controller (ELC), enabling 18 event inputs to trigger up to 6 peripheral functions directly - including timer starts, ADC conversions, and DMA transfers - reducing interrupt latency and CPU load in real-time control loops.
Key Specifications

FAQ
What is the maximum operating frequency of the R5F11EAAASP#30?
The R5F11EAAASP#30 supports a maximum high-speed on-chip oscillator frequency of 24 MHz (±2% accuracy) and a maximum external crystal oscillator frequency of 20 MHz. When using the high-speed on-chip oscillator at 24 MHz, the minimum instruction execution time is 0.04167 µs - enabling real-time response in motor control and sensor fusion applications where the R5F11EAAASP#30 operates reliably across its full -40°C to +85°C temperature range.
Does the R5F11EAAASP#30 support in-system programming?
Yes, the R5F11EAAASP#30 supports self-programming of its 16 KB flash memory via on-chip debug interface or user firmware using the Flash Self-Programming Library. This capability allows field firmware updates without external programmers. The R5F11EAAASP#30 implements flash shield window protection and block erase prohibition to prevent accidental overwrite - critical for maintaining functional safety in deployed R5F11EAAASP#30-based systems.
How many analog input channels does the R5F11EAAASP#30 provide?
The R5F11EAAASP#30 provides 8 analog input channels: ANI0 through ANI3 (on P20–P23), and ANI16 through ANI19 (on P00, P01, P147, and P120). All channels support 10-bit A/D conversion with selectable reference voltages (VDD, internal 1.45 V, or AVREFP/AVREFM differential). The R5F11EAAASP#30 also integrates a temperature sensor and programmable gain amplifier - enabling direct thermal compensation and low-level signal amplification without external components.
What power-saving modes are available on the R5F11EAAASP#30?
The R5F11EAAASP#30 offers HALT mode (0.42 µA), STOP mode (0.23 µA), and SNOOZE mode - all retaining RAM content and selected peripheral states. In STOP mode, the low-speed on-chip oscillator (15 kHz) remains active to drive the watchdog timer and interval timer, allowing precise wake-up intervals. The R5F11EAAASP#30 exits STOP mode via external interrupt (e.g., INTP0–INTP5) or RTC alarm, making it ideal for intermittent-sensing applications where the R5F11EAAASP#30 achieves sub-µA average current in duty-cycled deployments.
Is the R5F11EAAASP#30 pin-compatible with other RL78/G1G variants?
No - the R5F11EAAASP#30 uses a 30-pin LSSOP package, while other RL78/G1G variants use 32-pin LQFP (e.g., R5F11EBAAFP#30) or 44-pin LQFP (e.g., R5F11EFAAFP#30). Pin functions are not interchangeable across packages due to differing I/O counts and peripheral mappings. However, the R5F11EAAASP#30 shares identical register-level peripheral configuration and instruction set with other RL78/G1G devices, enabling firmware portability when migrating to higher-pin-count variants.
