Technical Context
The R5F11EA8ASP#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and support for multiply/divide/accumulate instructions across a 1 MB address space. It integrates a 12-bit interval timer, watchdog timer, and event link controller (ELC) capable of linking 18 event signals to peripheral functions.
Its analog subsystem includes an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor (HS mode only), dual comparators with selectable 8-bit DAC reference, and a single PGA channel. Power management features include on-chip POR, 6-level LVD, and three low-power modes (HALT, STOP, SNOOZE) with sub-µA current draw.

FAQ
What is the maximum operating frequency of the R5F11EA8ASP#10?
The R5F11EA8ASP#10 supports a maximum high-speed on-chip oscillator frequency of 24 MHz (±2% accuracy) and an external crystal clock up to 20 MHz. Its minimum instruction execution time is 0.04167 µs at 24 MHz, enabling real-time response in sensor and control applications. The R5F11EA8ASP#10 maintains full functionality across its 2.7–5.5 V supply range at these speeds.
Does the R5F11EA8ASP#10 support in-system programming?
Yes, the R5F11EA8ASP#10 supports self-programming via its on-chip debug interface and flash shield window function. This allows secure firmware updates in the field without external programmers. The R5F11EA8ASP#10 uses a 1 KB flash block size and prohibits partial block erasure to protect intellectual property during reprogramming.
How many analog input channels does the R5F11EA8ASP#10 have?
The R5F11EA8ASP#10 provides 8 dedicated analog input channels: ANI0–ANI3 on Port 2, ANI16–ANI19 on Ports 0/12/14, with 10-bit resolution and internal 1.45 V reference. Temperature sensor and AVREFP/AVREFM inputs are also accessible, all operating across the full 2.7–5.5 V VDD range in HS mode.
What low-power modes are available on the R5F11EA8ASP#10?
The R5F11EA8ASP#10 offers HALT, STOP, and SNOOZE modes. STOP mode draws 0.42 µA typical (VDD = 3.0 V, TA = 25°C), HALT mode consumes ~1.2 µA, and SNOOZE allows selected peripherals (e.g., ADC, UART) to operate while CPU sleeps. All modes retain RAM content and support wake-up via INTP0–INTP5 or RTC alarm.
Is the R5F11EA8ASP#10 pin-compatible with other RL78/G1G variants?
The R5F11EA8ASP#10 shares the same 30-pin LSSOP footprint and pinout with R5F11EAAASP#10, differing only in flash size (8 KB vs. 16 KB). It is not pin-compatible with 32-pin or 44-pin RL78/G1G variants like R5F11EB8AFP#10 or R5F11EF8AFP#10 due to different package dimensions and I/O allocations.
