Product details
Overview
R5F107ACGSP#X0 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-channel ADC, 2-channel DAC), three operational amplifiers (two with analog MUX), internal voltage reference (1.5/1.8/2.048/2.5 V), and real-time clock 2 (RTC2) with calendar and alarm. It operates from 1.8 V to 3.6 V across –40°C to +85°C and targets ultra-low-power LCD-based consumer devices such as smart meters and portable health monitors.
For engineers reviewing the R5F107ACGSP#X0 datasheet, R5F107ACGSP#X0 pinout, R5F107ACGSP#X0 application, or R5F107ACGSP#X0 equivalent, key selection criteria include its 128 KB flash / 5.5 KB RAM configuration, 100-pin LFQFP package with dedicated LCD drive pins (COM0–COM7, SEG0–SEG44), true low-power HALT mode (0.68 μA), and integrated analog signal chain for sensor front-end and display control without external components.
Technical Context
The R5F107ACGSP#X0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz HOCO or 30.5 μs at 32.768 kHz subsystem clock). It integrates a 12-bit interval timer, watchdog timer, and event link controller (ELC) supporting 22 event inputs to trigger peripheral functions without CPU intervention.
Its analog subsystem includes a 12-bit A/D converter with internal 1/2 AVDD reference and temperature sensor, a 12-bit D/A converter with rail-to-rail output range (0.35 V to AVDD – 0.47 V), and three op-amps - two configured as rail-to-rail with programmable analog MUX (MUX00–MUX03, MUX10–MUX13) and one general-purpose amplifier - all sharing a common AVDD/AVSS domain.

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-channel ADC | Not suitable where internal 2.048 V reference is required for precision ADC/DAC operation | Select R5F107ACGSP#X0 when VREFOUT and full 14-channel ADC capability are mandatory |
| RL78/G14 R5F104PJAFB#30 | RL78/G14 family; 100-pin LFQFP, 128 KB flash, but no integrated LCD controller/driver and only 8-channel ADC | Requires external LCD driver IC and additional op-amp/DAC components for equivalent functionality | Choose R5F107ACGSP#X0 for LCD-centric designs to avoid added component count and layout complexity |
Compared with R5F11MPGAFB#30 and RL78/G14 R5F104PJAFB#30, the R5F107ACGSP#X0 uniquely delivers full 14-channel ADC, VREFOUT, and LCD driver in one 100-pin package - reducing system-level BOM cost and PCB area by eliminating ≥5 external analog and display components.

FAQ
What is the maximum LCD segment count supported by the R5F107ACGSP#X0?
The R5F107ACGSP#X0 supports up to 45 segment outputs (SEG0–SEG44) and 8 common outputs (COM0–COM7), enabling configurations up to 360 segments (45 × 8) using internal voltage boosting or capacitor-split methods. This matches the highest LCD drive capability documented for the 100-pin RL78/L1A variants in the R01DS0280EJ0130 datasheet.
Does the R5F107ACGSP#X0 include an internal voltage reference for ADC and DAC?
Yes, the R5F107ACGSP#X0 provides an internal voltage reference output (VREFOUT) with selectable voltages of 1.5 V, 1.8 V, 2.048 V, or 2.5 V (typical). This reference is explicitly used by both the 12-bit A/D and D/A converters, eliminating the need for external reference ICs in precision measurement and output applications.
What is the lowest power consumption mode available on the R5F107ACGSP#X0?
The R5F107ACGSP#X0 achieves 0.68 μA in HALT mode with RTC2 and low-voltage detector (LVD) active - the lowest documented operating current for this part. This mode retains RAM content and enables wake-up via RTC alarm or external interrupt, making it ideal for battery-powered LCD instruments requiring multi-year operation.
How many operational amplifiers does the R5F107ACGSP#X0 integrate, and what are their key capabilities?
The R5F107ACGSP#X0 integrates three operational amplifiers: one general-purpose amplifier (AMP0) and two rail-to-rail amplifiers (AMP1, AMP2) each with a 4-input analog multiplexer (MUX00–MUX03, MUX10–MUX13). These support programmable gain configurations, sensor signal conditioning, and direct connection to the 14-channel ADC without external components.
Is the R5F107ACGSP#X0 pin-compatible with other RL78/L1A 100-pin variants like R5F11MPGAFB#30?
Yes, the R5F107ACGSP#X0 shares the identical 100-pin LFQFP package (PLQP0100KB-B), pinout, and mechanical footprint with other RL78/L1A 100-pin parts including R5F11MPGAFB#30. However, functional differences exist - notably R5F107ACGSP#X0 includes VREFOUT and full 14-channel ADC support not present in R5F11MPGAFB#30 - so firmware and schematic validation is required despite physical compatibility.
