Product details
Overview
R5F104AEASP#30 from Renesas is a 30-pin LSSOP-packaged RL78/G14 16-bit microcontroller with 48 KB flash, 5.5 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, RTC, and on-chip oscillators for battery-powered industrial sensor nodes.
For engineers reviewing the R5F104AEASP#30 datasheet, R5F104AEASP#30 pinout, R5F104AEASP#30 application, or R5F104AEASP#30 equivalent, key selection criteria include its 30-pin LSSOP package, -40°C to +85°C industrial temperature grade (A-field), 48 KB code flash size, integrated 10-bit ADC with 16 analog inputs, and support for LIN-bus-capable UART channels in compact embedded control designs.
Technical Context
The R5F104AEASP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It uses a dedicated low-speed on-chip oscillator for watchdog timer operation and supports background data flash rewriting (BGO) while executing program code.
Its peripheral set includes Timer Array Unit (TAU) with up to 8 channels, Real-time Clock with calendar and alarm, Event Link Controller (ELC) for hardware-triggered peripheral chaining, and Data Transfer Controller (DTC) supporting block and chain transfers activated by interrupt sources - enabling deterministic real-time response without CPU intervention.

FAQ
What is the maximum operating frequency and core architecture of the R5F104AEASP#30?
The R5F104AEASP#30 operates at up to 32 MHz using the RL78 16-bit CISC CPU core with a 3-stage pipeline. It achieves 44 DMIPS performance and supports configurable instruction timing - from 0.03125 µs at full speed to 30.5 µs in ultra-low-speed mode - enabling precise trade-offs between processing throughput and power consumption in the R5F104AEASP#30.
How much flash and RAM does the R5F104AEASP#30 integrate, and what are their usage models?
The R5F104AEASP#30 integrates 48 KB of code flash memory and 5.5 KB of on-chip RAM. The code flash stores application firmware and supports self-programming with boot swapping and flash shield window protection. The 4 KB data flash enables EEPROM-like nonvolatile storage for calibration data or configuration parameters, with background operation allowing concurrent program execution - all critical for field-upgradable firmware in the R5F104AEASP#30.
Does the R5F104AEASP#30 support LIN communication, and which peripherals enable it?
Yes, the R5F104AEASP#30 supports LIN communication through its UART channels, specifically UART2 (pins P13/P14) and UART0 (pins P50/P51), both of which are LIN-bus capable per the RL78/G14 datasheet. These UART modules include LIN-specific features such as automatic sync-break detection and checksum generation, making the R5F104AEASP#30 suitable for automotive body electronics and industrial sub-networks without requiring external LIN transceivers.
What low-power modes are available on the R5F104AEASP#30, and what are their typical current draws?
The R5F104AEASP#30 offers HALT mode (66 μA/MHz), STOP mode (0.60 μA), and SNOOZE mode - all optimized for minimal power consumption while retaining essential functionality like RTC and LVD operation. In STOP mode, only the 32.768 kHz subsystem clock remains active, enabling wake-up via external interrupt or RTC alarm. This ultra-low quiescent current makes the R5F104AEASP#30 ideal for battery-powered applications requiring multi-year operational life.
What is the analog capability of the R5F104AEASP#30, including ADC resolution, channels, and references?
The R5F104AEASP#30 features a 10-bit successive approximation register (SAR) ADC with up to 16 analog input channels (ANI0–ANI19, excluding reserved pins). It includes an internal 1.45 V reference voltage and supports differential inputs using AVREFP/AVREFM pins. The ADC operates across the full 1.6–5.5 V supply range, enabling direct ratiometric measurement of resistive sensors and thermistors - a key capability for precision analog sensing in the R5F104AEASP#30.
