Product details
Overview
R5F107DEMSP#V0 from Renesas is an RL78/L1A-series 16-bit microcontroller with integrated LCD controller/driver (45 segment/8 common), 12-bit A/D and D/A converters (14/2 channels), rail-to-rail operational amplifiers (3 channels, 2 with analog MUX), internal voltage reference (1.5–2.5 V), and real-time clock 2 with calendar function. It operates from 1.8 V to 3.6 V at -40°C to +85°C and targets battery-powered LCD-based consumer devices such as smart meters and portable medical displays.
For engineers reviewing the R5F107DEMSP#V0 datasheet, R5F107DEMSP#V0 pinout, R5F107DEMSP#V0 application, or R5F107DEMSP#V0 equivalent, key selection criteria include its 100-pin LFQFP package, 128 KB flash/8 KB data flash/5.5 KB RAM memory configuration, ultra-low power HALT mode (0.68 μA), and dual-clock domain support (24 MHz high-speed on-chip oscillator ±1.0% accuracy, 32.768 kHz subsystem crystal).
Technical Context
The R5F107DEMSP#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 33 DMIPS @ 24 MHz. Its peripheral set is optimized for LCD-centric systems: the LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods; the A/D converter includes internal 1/2 AVDD reference and temperature sensor; and the D/A converter delivers 0.35 V to AVDD – 0.47 V output range.
Power management integrates POR, LVD (10-level selectable), and three low-power modes (HALT, STOP, SNOOZE). The event link controller (ELC) links 22 event signals to peripherals, while the data transfer controller (DTC) handles background transfers from 30 interrupt sources-including ADC completion, UART receive, and timer overflow-without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11MPGAFB#30 | Same RL78/L1A family, identical 100-pin LFQFP package, 128 KB flash, but lacks internal voltage reference output (VREFOUT) and has only 10 A/D channels | Not suitable where programmable 1.5–2.5 V reference is required for external analog circuitry or precision sensor biasing | Select R5F107DEMSP#V0 when VREFOUT and full 14-channel A/D are needed; choose R5F11MPGAFB#30 only if reference output is unused and cost reduction is critical |
| RA2A1GBM20FB#AC0 | Arm® Cortex®-M23 core, 12-bit A/D (24 ch), 12-bit D/A (2 ch), but no integrated LCD controller; requires external segment drivers | Requires external LCD bias IC and additional PCB routing; better suited for color TFT or high-segment-count displays beyond 45×8 | Choose R5F107DEMSP#V0 for turnkey LCD integration and ultra-low power; select RA2A1GBM20FB#AC0 only when Arm ecosystem compatibility or higher compute throughput is mandatory |
Compared with R5F11MPGAFB#30, R5F107DEMSP#V0 adds VREFOUT and 4 extra A/D channels-critical for sensor-rich LCD panels. Against RA2A1GBM20FB#AC0, it trades Arm compatibility for lower BOM cost, smaller footprint, and guaranteed LCD timing control via hardware acceleration.

FAQ
What is the maximum LCD segment count supported by the R5F107DEMSP#V0?
The R5F107DEMSP#V0 supports up to 45 segment outputs and 8 common outputs, configurable via internal voltage boosting, capacitor split, or external resistance division methods. This enables direct drive of alphanumeric or custom segment LCDs without external bias ICs, as confirmed in the RL78/L1A datasheet Section 1.6 and block diagram on Page 8.
Does the R5F107DEMSP#V0 include an internal voltage reference for analog peripherals?
Yes, the R5F107DEMSP#V0 provides a programmable internal voltage reference (VREFOUT) with selectable output voltages of 1.5 V, 1.8 V, 2.048 V, or 2.5 V (typical), usable as the reference source for both its 12-bit A/D and D/A converters. This is documented in Section 1.1 Features and Section 1.6 Outline of Functions of the RL78/L1A datasheet.
What low-power modes does the R5F107DEMSP#V0 support, and what is the lowest current consumption?
The R5F107DEMSP#V0 supports HALT, STOP, and SNOOZE modes. In HALT mode with RTC2 and LVD active, it consumes just 0.68 μA-verified in Section 1.1 Features and electrical specifications table on Page 14 of the RL78/L1A datasheet. This enables multi-year battery operation in metering and portable applications.
How many operational amplifiers does the R5F107DEMSP#V0 integrate, and what are their key capabilities?
The R5F107DEMSP#V0 integrates three rail-to-rail operational amplifiers: one general-purpose (AMP0) and two with analog MUX switches (AMP1 and AMP2), each supporting four input selections. These are designed for sensor signal conditioning, active filtering, and programmable gain stages-details confirmed in Sections 1.1, 1.6, and the block diagram on Page 8.
Is the R5F107DEMSP#V0 pin-compatible with other RL78/L1A variants like R5F11MPGAFB#30?
No, the R5F107DEMSP#V0 is not pin-compatible with R5F11MPGAFB#30. Although both are 100-pin LFQFP devices in the RL78/L1A family, the R5F107DEMSP#V0 is a distinct orderable part with unique feature enablement-including VREFOUT and full 14-channel A/D-requiring verification against the specific pin configuration diagrams in Section 1.3.2 of the datasheet.
