Product details
Overview
R5F107ACMSP#V0 from Renesas is an RL78/L1A 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), and real-time clock 2 (RTC2) with calendar support - designed for ultra-low-power LCD-based consumer instrumentation operating from 1.8 V to 3.6 V.
For engineers reviewing the R5F107ACMSP#V0 datasheet, R5F107ACMSP#V0 pinout, R5F107ACMSP#V0 application, or R5F107ACMSP#V0 equivalent, key selection criteria include its 128 KB flash/8 KB data flash memory, 79 I/O pins in 100-pin LFQFP package, HALT-mode current of 0.68 μA, and integrated voltage reference (1.5–2.5 V) for precision analog subsystems.
Technical Context
The RL78 CPU core implements a CISC architecture with 3-stage pipeline, supporting multiply/divide and MAC instructions, 1 MB address space, and configurable instruction execution time (0.04167 μs at 24 MHz HOCO or 30.5 μs at 32.768 kHz subsystem clock). It integrates event link controller (ELC) for hardware-triggered peripheral chaining and data transfer controller (DTC) with 30 activation sources.
Analog subsystem includes three independent op-amps (AMP0–AMP2), one comparator, internal 1/2 AVDD reference, and selectable LCD drive methods (internal boosting, capacitor split, external resistor division). Power management features POR, LVD (10-level detection), and multiple low-power modes (HALT, STOP, SNOOZE) with RTC2 retention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11MPGAFB | Same RL78/L1A family, identical 100-pin LFQFP package, 128 KB flash, but lacks internal voltage reference output (VREFOUT) | Requires external reference for high-accuracy A/D or D/A; unsuitable where internal 1.5–2.5 V reference is critical | Select R5F107ACMSP#V0 when VREFOUT-driven precision analog design is required |

FAQ
What is the maximum LCD segment count supported by R5F107ACMSP#V0?
R5F107ACMSP#V0 supports up to 45 segment outputs and 8 common outputs, enabling multiplexed LCD drive for displays up to 45 × 8 segments. This configuration is confirmed in the RL78/L1A datasheet Section 1.6 and applies specifically to 100-pin variants like R5F107ACMSP#V0. The device allows dynamic switching between internal voltage boosting, capacitor split, and external resistance division drive methods.
Does R5F107ACMSP#V0 include an internal voltage reference for A/D and D/A converters?
Yes, R5F107ACMSP#V0 provides an internal voltage reference (VREFOUT) with selectable output voltages of 1.5 V, 1.8 V, 2.048 V, or 2.5 V (typical). This reference is explicitly documented as usable for both the 12-bit A/D and D/A converters, eliminating the need for external reference ICs in precision analog designs.
What low-power modes are available on R5F107ACMSP#V0, and what is the lowest current consumption?
R5F107ACMSP#V0 offers HALT, STOP, and SNOOZE modes. Its lowest verified current is 0.68 μA in HALT mode with RTC2 and LVD active - a value specified in the datasheet under TA = –40°C to +85°C and VDD = 1.8–3.6 V. This enables multi-year battery operation in intermittent-readout applications like utility meters.
How many operational amplifiers does R5F107ACMSP#V0 integrate, and what are their key characteristics?
R5F107ACMSP#V0 integrates three operational amplifiers: one general-purpose (AMP0) and two rail-to-rail types (AMP1, AMP2) with integrated analog MUX (4 inputs per channel). All three support differential input configurations and are directly connected to the 14-channel A/D and 2-channel D/A subsystems, enabling sensor signal conditioning without external op-amp components.
Is R5F107ACMSP#V0 pin-compatible with other RL78/L1A 100-pin variants such as R5F11MPGAFB?
R5F107ACMSP#V0 shares the same 100-pin LFQFP package (PLQP0100KB-B) and pinout as R5F11MPGAFB and other RL78/L1A 100-pin members. However, functional differences exist - notably R5F107ACMSP#V0 includes VREFOUT and full 45-segment LCD support, while R5F11MPGAFB omits VREFOUT. Pin compatibility enables mechanical drop-in replacement, but firmware validation is required due to feature-set variations.
