Product details
Overview
R5F107ACGSP#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 (RTC2) with calendar and alarm. It operates from 1.8 V to 3.6 V at -40°C to +85°C and targets ultra-low-power LCD-based consumer devices such as blood glucose meters and portable medical displays.
For engineers reviewing the R5F107ACGSP#V0 datasheet, R5F107ACGSP#V0 pinout, R5F107ACGSP#V0 application, or R5F107ACGSP#V0 equivalent, this page delivers verified technical context, validated pin functions, confirmed low-power operating modes (HALT: 0.68 μA, SNOOZE: 70.8 μA/MHz), exact LCD drive capability (capacitor-split/boosting methods), and real-world alternative selection guidance for LCD MCU migration paths.
Technical Context
The R5F107ACGSP#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs @ 24 MHz HOCO or 30.5 μs @ 32.768 kHz subsystem clock). It integrates a 12-bit interval timer, watchdog timer, event link controller (22 input events), and data transfer controller (30 activation sources) for autonomous peripheral coordination without CPU intervention.
Its analog subsystem includes three operational amplifiers (AMP0–AMP2), one comparator, and dual 12-bit converters sharing AVDD/AVSS rails and internal reference voltage (VREFOUT). The LCD controller supports internal boosting, capacitor-split, and external resistor division methods-configurable per application-and drives up to 45 segments with 8 commons using VL1–VL4 and CAPH/CAPL pins.

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 A/D | Not suitable where programmable VREFOUT or full 14-channel A/D is required for sensor calibration or multi-signal acquisition | Select R5F107ACGSP#V0 when VREFOUT and full analog channel count are mandatory; choose R5F11MPGAFB#30 only if cost optimization outweighs analog feature loss |
| R5F104PJGSP#V0 | RL78/G13 family, 100-pin LFQFP, 128 KB flash, no integrated LCD controller/driver, no VREFOUT, and only 8-channel A/D | Requires external LCD driver IC and reference voltage source; unsuitable for standalone LCD display systems | R5F104PJGSP#V0 fits non-LCD applications needing general-purpose I/O and UART; R5F107ACGSP#V0 is mandatory for integrated LCD + analog sensor systems |
Compared with R5F11MPGAFB#30 and R5F104PJGSP#V0, the R5F107ACGSP#V0 uniquely combines full 14-channel A/D, programmable VREFOUT, and 45×8 LCD drive in a single 100-pin package-enabling compact, low-BOM designs for battery-powered medical and industrial displays where analog precision and embedded display control are co-dependent.

FAQ
What is the maximum LCD segment count supported by the R5F107ACGSP#V0?
The R5F107ACGSP#V0 supports up to 45 segment outputs and 8 common outputs, enabling drive of multiplexed LCDs with up to 360 segments (45 × 8). This configuration is confirmed in the RL78/L1A datasheet Section 1.6 for 100-pin products and applies directly to the R5F107ACGSP#V0. Segment mapping is configurable via LCD control registers and supports internal voltage boosting, capacitor-split, or external resistor division methods.
Does the R5F107ACGSP#V0 include an internal voltage reference for its A/D and D/A converters?
Yes, the R5F107ACGSP#V0 includes an internal voltage reference generator (VREFOUT) that outputs selectable voltages of 1.5 V, 1.8 V, 2.048 V, or 2.5 V (typical values). This reference is explicitly usable for both the 12-bit A/D converter and the 12-bit D/A converter, as stated in the "Voltage reference" section of the datasheet. It eliminates the need for external reference ICs in precision analog measurement and output applications.
What low-power modes does the R5F107ACGSP#V0 support, and what are their typical current draws?
The R5F107ACGSP#V0 supports HALT, STOP, and SNOOZE modes. HALT mode draws 0.68 μA (with RTC2 and LVD active), STOP mode draws 0.92 μA (RTC2 off), and SNOOZE mode consumes 70.8 μA/MHz during active operation. These values are measured at VDD = 1.8–3.6 V and TA = -40°C to +85°C, and are specified in the "Ultra-low power consumption technology" section of the RL78/L1A datasheet.
How many operational amplifiers does the R5F107ACGSP#V0 integrate, and what are their key capabilities?
The R5F107ACGSP#V0 integrates three operational amplifiers: AMP0, AMP1, and AMP2. AMP0 and AMP1 are rail-to-rail with analog MUX support (2 inputs each), while AMP2 is a general-purpose rail-to-rail op-amp. All three support programmable gain and offset configurations, and their inputs/outputs are mapped to dedicated pins (e.g., AMP0+ = P21, AMP0- = P23, AMP0O = P20), enabling flexible sensor signal conditioning without external op-amp ICs.
Is the R5F107ACGSP#V0 pin-compatible with other RL78/L1A 100-pin variants like R5F11MPGAFB#30?
No, the R5F107ACGSP#V0 is not pin-compatible with R5F11MPGAFB#30. Although both are 100-pin LFQFP devices in the RL78/L1A family, the R5F107ACGSP#V0 includes additional analog features-such as VREFOUT, full 14-channel A/D, and enhanced op-amp MUX routing-that require distinct pin assignments. Pin compatibility is not claimed in Renesas documentation, and direct substitution would require PCB redesign due to functional pin differences.
