Description

Product Overview

The R5F1007EANA#40 is an RL78/G10 8/16-bit microcontroller from Renesas Electronics, featuring 8KB Flash, 512 bytes RAM, and an 8-pin DIP package. It operates at up to 32MHz with ultra-low power consumption (135uA at 1MHz, 2.5V). Despite its small 8-pin form factor, it integrates an 8-bit timer, comparator, and I2C/SPI communication interface, making it ideal for space-constrained, battery-powered sensor and control applications.

The R5F1007EANA#40 is an RL78/G10 microcontroller from Renesas, offering 8KB Flash and 512 bytes RAM in an 8-pin DIP package. With ultra-low power consumption of just 135uA/MHz and 0.57uA in STOP mode, it is optimized for battery-powered applications. Despite its tiny form factor, it integrates a comparator with internal reference, I2C/SPI communication, and an 8-bit timer, making it a cost-effective replacement for discrete analog and logic circuits.

The R5F1007EANA#40 operates on Renesas’ RL78 core, which implements a CISC instruction set compatible with both 78K and R8C architectures. The CPU executes instructions in a 1-2 byte format with 64 general-purpose registers, achieving high code density. Flash memory stores the program and can be self-programmed for firmware updates and data emulation. The built-in comparator compares an external pin voltage against an internal programmable reference (16 levels), enabling threshold detection without an external ADC. The serial interface supports I2C (up to 400 kHz Fast Mode) or SPI (up to 8 MHz) on shared pins, configured by software. Low-power modes include HALT (CPU stopped, peripherals active), STOP (all oscillators stopped, 0.57uA), and SNOOZE mode where the comparator can wake the CPU when a threshold is crossed. The interval timer provides periodic wake-up from STOP mode for sensor polling.
