Product details
Overview
UPD78F1145AGB-GAH-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KE3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 10-bit ADC (16 channels), UART, I²C, and timer modules. It operates at up to 20 MHz with supply voltage range of 2.7–5.5 V and targets industrial control and sensor interface applications.
For engineers reviewing the UPD78F1145AGB-GAH-AX datasheet, UPD78F1145AGB-GAH-AX pinout, UPD78F1145AGB-GAH-AX application, or UPD78F1145AGB-GAH-AX equivalent, key selection considerations include Flash endurance (100,000 write/erase cycles), operating temperature range (−40°C to +85°C), and QFP-100 package compatibility with legacy 78K0R toolchains and debug infrastructure.
Technical Context
The UPD78F1145AGB-GAH-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture. It supports real-time interrupt handling via 16 priority-level vectors and includes a watchdog timer with independent clock source for system reliability.
On-chip peripheral integration includes a 10-bit successive-approximation ADC with sample-and-hold, four 16-bit timer/counters (two with PWM output), and dual serial interfaces - one UART with LIN support and one I²C-compatible interface supporting standard/fast-mode speeds up to 400 kbps.

FAQ
What is the maximum operating frequency of the UPD78F1145AGB-GAH-AX?
The UPD78F1145AGB-GAH-AX supports a maximum CPU clock frequency of 20 MHz when powered at 4.5–5.5 V. At lower supply voltages (2.7–4.4 V), the maximum guaranteed frequency is 10 MHz per electrical specifications in the 78K0R/KE3 User's Manual U17854EJ9V0UD. This scaling ensures stable timing margins across its full voltage range.
Does the UPD78F1145AGB-GAH-AX include a hardware LIN transceiver?
No, the UPD78F1145AGB-GAH-AX does not integrate a LIN physical layer transceiver. However, it contains dedicated LIN protocol support in UART0 - including automatic sync-break detection, checksum calculation, and identifier filtering - enabling seamless interface with external LIN transceivers such as the R2A25112NGL.
Can the UPD78F1145AGB-GAH-AX execute code from RAM?
Yes, the UPD78F1145AGB-GAH-AX supports RAM execution via the 78K0R CPU's ability to load program counter values from RAM addresses. This capability is used during firmware updates and real-time patching, though the primary execution path remains Flash-resident code due to performance and non-volatility requirements.
What debug interface does the UPD78F1145AGB-GAH-AX support?
The UPD78F1145AGB-GAH-AX supports on-chip debugging via the single-wire debug (SWD) interface using the QB-MINI2 emulator. It is fully compatible with RA78K0R assembler and CC78K0R C compiler toolchains, and supports breakpoints, watchpoints, and real-time register inspection without halting peripheral operation.
Is the UPD78F1145AGB-GAH-AX qualified for automotive applications?
The UPD78F1145AGB-GAH-AX carries a Standard quality grade per Renesas documentation and is intended for industrial applications. While it meets AEC-Q100 stress test conditions in some configurations, it is not officially certified for automotive use; Renesas recommends the RL78/F1x or RH850 families for production automotive ECUs requiring full AEC-Q100 Grade 2 qualification.
