Product details
Overview
UPD75P3116GC-8BS-A from Renesas Electronics is a 4-bit single-chip microcontroller with on-chip one-time PROM (16384 × 8 bits), 512 × 4-bit RAM, integrated LCD controller/driver supporting up to 24 segments, and programmable timers - designed for low-power embedded control in portable instrumentation and consumer display systems.
For engineers reviewing the UPD75P3116GC-8BS-A datasheet, UPD75P3116GC-8BS-A pinout, UPD75P3116GC-8BS-A application, or UPD75P3116GC-8BS-A equivalent, key selection considerations include its 1.8–5.5 V supply range, software-configurable internal pull-up resistors on 19 I/O pins, 64-pin LQFP (14 × 14 mm) package, Mk I/Mk II mode compatibility with µPD753108 firmware, and lead-free compliance indicated by the "-A" suffix.
Technical Context
The UPD75P3116GC-8BS-A implements a QTOP architecture with dual-clock system: main oscillator (ceramic/crystal, 4.19/6.0 MHz) and subsystem crystal (32.768 kHz), enabling STOP/HALT standby modes. Its CPU executes instructions in 0.67–15.3 µs depending on clock source and division ratio.
It integrates a full-featured LCD controller with selectable duty/bias (static to 1/4 duty), segment/common outputs (S0–S23, COM0–COM3), and dedicated LCD power rails (VLC0–VLC2, BIAS). The 5-channel timer subsystem includes three 8-bit timer/event counters (cascadable to 16-bit), basic interval/watchdog timer, and watch timer - all supporting vectored interrupts.

| RESET | Active-low reset input | Asynchronous reset signal; must be held low ≥100 ns after power stabilization. |
| VPP | PROM programming voltage | +12.5 V required only during one-time programming; tied to VDD during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| One-time PROM memory | Enables user-programmable firmware for evaluation and low-volume production without mask ROM lead time or cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UPD75P3116GC-8BS | Same die and functionality; differs only in RoHS compliance - lacks lead-free plating ("–A" suffix). | Not suitable for new designs targeting EU RoHS or China RoHS compliance. | Select UPD75P3116GC-8BS-A for all new designs requiring lead-free manufacturing. |
| UPD75P3116GK-8A8 | Identical core and features; packaged in 64-pin LQFP (12 × 12 mm) with 0.65 mm pitch instead of 14 × 14 mm / 0.8 mm. | Requires PCB layout revision due to smaller footprint and tighter pitch; may impact thermal dissipation in high-duty-cycle operation. | Choose UPD75P3116GK-8A8 only when board space constraints justify re-layout and assembly process validation. |
Compared with UPD75P3116GC-8BS-A, the non-lead-free GC-8BS variant requires exemption documentation for regulated markets, while the GK-8A8 variant trades package size for assembly complexity - making UPD75P3116GC-8BS-A the optimal choice for RoHS-compliant, production-ready designs with standard LQFP handling.

FAQ
What is the programming voltage requirement for UPD75P3116GC-8BS-A?
The UPD75P3116GC-8BS-A requires +12.5 V applied to the VPP pin during one-time PROM programming. During normal operation, VPP must be directly connected to VDD. This voltage is not used in run mode and does not affect standard MCU functionality - it is strictly for initial firmware loading.
Does UPD75P3116GC-8BS-A support in-circuit debugging?
No, the UPD75P3116GC-8BS-A does not support in-circuit debugging. It is a one-time programmable device with no debug interface or bootloader; firmware must be verified externally before programming, and no runtime code modification is possible after PROM write.
How many I/O pins on UPD75P3116GC-8BS-A support internal pull-up resistors?
UPD75P3116GC-8BS-A supports internal pull-up resistors on 19 I/O pins: 7 CMOS inputs (P00, P10–P13, P30–P31), 12 CMOS I/Os (P20–P23, P32–P33, P60–P63, P80–P83, P90–P93), configurable via software registers in 3- or 4-bit groups.
Can UPD75P3116GC-8BS-A drive a 1/4-duty LCD without external components?
Yes, UPD75P3116GC-8BS-A natively supports 1/4-duty (1/3 bias) LCD operation using its internal LCD controller. Configuration is done via software registers; no external resistors or capacitors are needed for basic bias generation when using the on-chip VLC0–VLC2 and BIAS outputs.
What is the difference between Mk I and Mk II modes in UPD75P3116GC-8BS-A?
Mk I mode (SBS3 = 1) matches µPD753108 instruction timing and stack behavior (2-byte stack), while Mk II mode (SBS3 = 0) extends stack depth to 3 bytes and adds BRA/CALLA instructions - improving compatibility with larger firmware but adding 1 cycle to CALL/CALLF execution. Mode is selected at runtime via the SBS register.
