Product details
Overview
UPD78F1165AGC-UEU-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 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1165AGC-UEU-AX datasheet, UPD78F1165AGC-UEU-AX pinout, UPD78F1165AGC-UEU-AX application, or UPD78F1165AGC-UEU-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), and support for low-power stop modes with wake-up via external interrupt or peripheral event.
Technical Context
The UPD78F1165AGC-UEU-AX implements the 78K0R CPU core with 16-bit ALU, 32-bit accumulator support, and Harvard architecture with separate instruction/data buses. It integrates a programmable 8-bit watchdog timer, power-on reset circuit, and on-chip voltage regulator (REGC pin) supporting internal 3.3 V supply generation from 5 V input.
Peripheral subsystems include a 16-bit multifunction timer array (TAU) with capture/compare/PWM output capability, a 10-bit successive-approximation ADC with sample-and-hold and hardware-triggered conversion, and dual serial interface units supporting asynchronous UART and synchronous I²C master/slave operation.

FAQ
What is the maximum operating frequency of the UPD78F1165AGC-UEU-AX?
The UPD78F1165AGC-UEU-AX supports a maximum system clock frequency of 20 MHz when using the on-chip PLL with an external crystal oscillator. Without PLL, the maximum frequency is 16 MHz using the high-speed on-chip oscillator. All timing specifications in the datasheet - including ADC conversion time and timer resolution - are validated at this rated frequency.
Does the UPD78F1165AGC-UEU-AX include a hardware debug interface?
Yes, the UPD78F1165AGC-UEU-AX supports on-chip debugging via the single-wire debug (SWD) interface compliant with Renesas' standard QB-MINI2 and E2 emulator platforms. This enables full breakpoint, watchpoint, and real-time register inspection without requiring dedicated debug pins beyond the standard RESET and clock lines.
What is the Flash endurance specification for UPD78F1165AGC-UEU-AX?
The UPD78F1165AGC-UEU-AX guarantees 100,000 write/erase cycles per Flash sector and 10 years of data retention at +85°C. This endurance rating applies to all 128 KB of on-chip Flash memory and is verified under Renesas' Standard quality grade test conditions per JESD22-A117.
Can UPD78F1165AGC-UEU-AX operate from a 3.3 V supply only?
Yes, the UPD78F1165AGC-UEU-AX operates across 2.7 V to 5.5 V, so it functions fully at 3.3 V. When powered at 3.3 V, the internal regulator (REGC) is bypassed, and VDD/EVDD must be supplied externally at 3.3 V ±10%. All I/Os remain 5 V tolerant, enabling mixed-voltage system interfacing.
Is the UPD78F1165AGC-UEU-AX RoHS compliant and lead-free?
Yes, the UPD78F1165AGC-UEU-AX is RoHS compliant and lead-free per EU Directive 2011/65/EU and Renesas' environmental compliance documentation. The "-AX" suffix in the part number explicitly denotes lead-free, halogen-free packaging meeting JEDEC JS-709C standards.
