Product details
Overview
UPD78F1175GF(R)-GAT-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KH3 family, designed for embedded control in industrial and consumer systems. It integrates 128 KB Flash memory, 8 KB RAM, a 10-bit ADC with 24 channels, 3x 16-bit timer/counters, and supports LIN bus communication via on-chip UART. It operates at up to 20 MHz and targets motor control, sensor interface, and appliance management applications.
For engineers reviewing the UPD78F1175GF(R)-GAT-AX datasheet, UPD78F1175GF(R)-GAT-AX pinout, UPD78F1175GF(R)-GAT-AX application, or UPD78F1175GF(R)-GAT-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), operating voltage range (2.7–5.5 V), integrated voltage regulator (REGC pin), LIN-compliant UART timing accuracy (±1.5% at 20 MHz), and support for low-power STOP mode with wake-up via external interrupt or RTC.
Technical Context
The UPD78F1175GF(R)-GAT-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It features dual-voltage domains: EVDD0/EVSS0 for I/O and EVDD1/EVSS1 for internal logic, enabling flexible power partitioning.
Its peripheral set includes a programmable 16-bit watchdog timer with independent clock source, 3-channel DMAC supporting memory-to-peripheral transfers, and an on-chip voltage regulator controller (REGC) that manages internal 3.3 V supply generation when external 5 V is applied - critical for mixed-signal stability in noise-sensitive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#30 | RL78/G13-based; 32 KB Flash, 4 KB RAM, lower power (0.52 μA STOP), but no built-in LIN UART - requires external transceiver | Better suited for ultra-low-power battery-operated nodes where LIN is not required | Select if energy budget is tighter than communication integration needs |
| UPD78F1154GC-GAD-AX | Same 78K0R/KH3 family; 96 KB Flash, 6 KB RAM, identical peripherals and pinout - direct subset variant | Matches cost-sensitive designs needing reduced memory footprint without feature trade-offs | Choose for drop-in replacement where 128 KB Flash is unnecessary |
Compared with UPD78F1175GF(R)-GAT-AX, R5F100PLAFB#30 offers superior low-power metrics but lacks integrated LIN timing support, while UPD78F1154GC-GAD-AX provides identical peripheral functionality in a smaller memory configuration - enabling cost optimization without redesign.

FAQ
What is the maximum operating frequency of the UPD78F1175GF(R)-GAT-AX?
The UPD78F1175GF(R)-GAT-AX operates at a maximum CPU clock frequency of 20 MHz, delivering 1.25 MIPS per MHz. This frequency is supported across the full 2.7–5.5 V supply range and ambient temperature range of −40°C to +85°C, as specified in Renesas Electrical Characteristics section of the U18432EJ5V0UD manual.
Does the UPD78F1175GF(R)-GAT-AX support in-system programming (ISP)?
Yes, the UPD78F1175GF(R)-GAT-AX supports in-system programming via its on-chip Flash memory, which allows firmware updates without removing the device from the PCB. The Flash is rated for 100,000 write/erase cycles and supports sector-level erasure, enabling safe field upgrades and bootloader implementation - confirmed in Section 3.1.1 of the U18432EJ5V0UD User's Manual.
What LIN protocol versions does the UPD78F1175GF(R)-GAT-AX UART support?
The UPD78F1175GF(R)-GAT-AX includes a dedicated LIN-compliant UART that supports LIN 2.0, 2.1, and 2.2 specifications. Its hardware handles sync-break detection, checksum calculation (classic and enhanced), and identifier filtering - eliminating software overhead and ensuring timing compliance without external transceiver dependency, as documented in Section 2.2.2 of the U18432EJ5V0UD manual.
How does the REGC pin function on the UPD78F1175GF(R)-GAT-AX?
The REGC pin on the UPD78F1175GF(R)-GAT-AX controls the internal voltage regulator: when driven high, it enables generation of a regulated 3.3 V supply from a 5 V external source for analog and digital circuitry; when low, the regulator is disabled and the device uses an externally supplied 3.3 V. This dual-mode operation is detailed in Section 2.2.21 and electrical characteristics tables of the U18432EJ5V0UD manual.
Is the UPD78F1175GF(R)-GAT-AX qualified for automotive applications?
No, the UPD78F1175GF(R)-GAT-AX is classified as a "Standard" quality grade device per Renesas documentation, intended for computers, office equipment, home appliances, and industrial robots - not for automotive or safety-critical systems. Automotive-qualified equivalents (e.g., RL78/F13 series) require explicit AEC-Q100 qualification and are separately designated in Renesas part numbering.
