Product details
Overview
R5F107DEGSP#X0 from Renesas is an RL78/L1A-series 16-bit microcontroller with integrated LCD controller/driver, 12-bit A/D and D/A converters, three operational amplifiers (two with analog MUX), internal voltage reference, and real-time clock 2. It operates from 1.8 V to 3.6 V, delivers 33 DMIPS at 24 MHz, and achieves ultra-low power consumption down to 70.8 μA/MHz and 0.68 μA in Halt mode - optimized for battery-powered LCD-based consumer devices such as smart meters and portable medical displays.
For engineers reviewing the R5F107DEGSP#X0 datasheet, R5F107DEGSP#X0 pinout, R5F107DEGSP#X0 application, or R5F107DEGSP#X0 equivalent, key selection considerations include its 48 KB flash / 5.5 KB RAM configuration, 80-pin LFQFP package with 59 I/Os, integrated LCD drive capability (up to 32 segments × 4 commons), and dual 12-bit analog converters supporting simultaneous sensor signal conditioning and feedback control.
Technical Context
The R5F107DEGSP#X0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated low-power subsystem clock domain (32.768 kHz XT1) for RTC2 and supports event-driven operation via the Event Link Controller (ELC) with 22 input events linked to peripheral functions.
Its analog subsystem includes a 12-bit A/D converter with 10 input channels (including internal ½ AVDD), a 12-bit D/A converter with two outputs (0.35 V to AVDD – 0.47 V), and rail-to-rail op-amps with programmable analog MUX routing - enabling single-chip sensor front-end and display driver functionality without external signal conditioning components.

The R5F107DEGSP#X0 supports up to 32 segment outputs and 4 common outputs in its 80-pin configuration, as confirmed in the RL78/L1A datasheet Section 1.6. This enables driving standard 4-digit, 7-segment displays or custom segmented LCDs used in energy meters and medical devices without external segment drivers.
Does the R5F107DEGSP#X0 include a hardware RTC with calendar function?
Yes, the R5F107DEGSP#X0 integrates Real-Time Clock 2 (RTC2) with full calendar support for 99 years, alarm functionality, and automatic clock correction - all operating independently in ultra-low-power Halt mode using the 32.768 kHz subsystem clock, as specified in Section 1.1 and 1.6 of the datasheet.
What are the analog reference voltage options for the A/D and D/A converters in the R5F107DEGSP#X0?
The R5F107DEGSP#X0 provides selectable internal reference voltages of 1.5 V, 1.8 V, 2.048 V, and 2.5 V (typical values), which can be used directly by both the 12-bit A/D and D/A converters - eliminating need for external reference ICs and improving measurement stability across voltage and temperature variations.
Can the R5F107DEGSP#X0 operate from a single 3.0 V coin cell battery?
Yes, the R5F107DEGSP#X0 operates across 1.8 V to 3.6 V, making it fully compatible with standard 3.0 V lithium coin cells (e.g., CR2032). Its 0.68 μA Halt mode current and ability to retain RTC2 and LVD functionality at 1.8 V ensure reliable multi-year operation in battery-powered LCD instruments.
How many operational amplifiers does the R5F107DEGSP#X0 integrate, and what are their key capabilities?
The R5F107DEGSP#X0 integrates three operational amplifiers: one general-purpose and two rail-to-rail types with integrated 4-input analog MUX switches (MUX00–MUX03 and MUX10–MUX13). These support programmable signal routing, sensor amplification, and filtering prior to A/D conversion - confirmed in Sections 1.1 and 1.6 of the datasheet.
