Product details
Overview
R5F11EA8ASP#70 from Renesas is an 8 KB flash, 1.5 KB RAM RL78/G1G 8-bit microcontroller in 30-pin LSSOP package, operating at 2.7–5.5 V with ultra-low-power STOP/HALT/SNOOZE modes. It integrates a 10-bit A/D converter (8 channels), 2-channel comparator, programmable gain amplifier, UART×2, simplified SPI (CSI), simplified I²C, 7×16-bit timers, and on-chip debug - deployed in battery-powered sensor nodes and home appliance control panels.
For engineers reviewing the R5F11EA8ASP#70 datasheet, R5F11EA8ASP#70 pinout, R5F11EA8ASP#70 application, or R5F11EA8ASP#70 equivalent, key selection criteria include its 30-pin LSSOP footprint, 8 KB code flash with self-programming capability, 26 I/O pins including analog inputs ANI0–ANI3 and ANI16–ANI19, and support for HS/LS system clock modes up to 24 MHz (on-chip oscillator) or 20 MHz (external crystal).
Technical Context
The R5F11EA8ASP#70 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and hardware multiply/divide/accumulate instructions. Its memory map spans 1 MB address space with 8 KB flash organized in 1 KB blocks, supporting flash shield window and block-erase prohibition for security.
Peripherals are coordinated via the Event Link Controller (ELC), which links 18 event sources to designated functions without CPU intervention. The high-speed on-chip oscillator offers selectable frequencies (1–24 MHz) with ±2.0% accuracy, while the low-speed on-chip oscillator runs at 15 kHz for watchdog and interval timing.

FAQ
What is the maximum operating frequency of the R5F11EA8ASP#70 using its internal oscillator?
The R5F11EA8ASP#70 supports a high-speed on-chip oscillator (HOCO) up to 24 MHz with ±2.0% accuracy across -40°C to +85°C. This enables minimum instruction execution time of 0.04167 µs. External crystal operation is limited to 20 MHz maximum for the main system clock.
Does the R5F11EA8ASP#70 support in-circuit debugging, and what are the constraints?
Yes, the R5F11EA8ASP#70 includes on-chip debug functionality accessible via TOOL0, TOOLRxD, and TOOLTxD pins. However, Renesas explicitly cautions against using this feature in mass-produced units due to finite flash rewrite endurance - debug use may exceed guaranteed erase cycles and compromise long-term reliability.
How many analog input channels does the R5F11EA8ASP#70 provide, and what are their voltage ranges?
The R5F11EA8ASP#70 provides 8 analog input channels: ANI0–ANI3 (P20–P23), ANI16–ANI19 (P00, P01, P147, P120). All support 10-bit resolution with full-scale range of VSS to VDD (2.7–5.5 V), and internal 1.45 V reference is available for ratiometric measurements.
Can the R5F11EA8ASP#70 drive LEDs directly, and what are the current limits per pin?
Yes, the R5F11EA8ASP#70 can drive LEDs directly via its CMOS I/O pins. Per-pin sink current is rated at 20 mA (typical), with absolute maximum of 40 mA. Total sink current across all pins must not exceed 150 mA. Pins P20–P27 are limited to 1 mA per pin and 5 mA total - avoid using them for LED drive.
What packaging and ordering options are available for the R5F11EA8ASP#70?
The R5F11EA8ASP#70 is supplied in 30-pin plastic LSSOP (0.65 mm pitch) in tray packaging (#10, #30, #70) or embossed tape (#50). The "SP" suffix denotes LSSOP; "#70" indicates tray packaging. It is rated for industrial temperature range (-40°C to +85°C) and RoHS compliant.
