Product details
Overview
UPD78F1162AGC-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 a maximum operating frequency of 20 MHz. It integrates UART, I²C, SPI, 16-bit timer arrays, ADC (10-bit, 12-channel), and operates from 2.7 V to 5.5 V supply. It is used in industrial control panels requiring deterministic real-time response and firmware-upgradable logic.
For engineers reviewing the UPD78F1162AGC-UEU-AX datasheet, UPD78F1162AGC-UEU-AX pinout, UPD78F1162AGC-UEU-AX application, or UPD78F1162AGC-UEU-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), built-in voltage regulator (REGC pin), and support for single-supply operation with internal clock oscillator (1 to 20 MHz).
Technical Context
The UPD78F1162AGC-UEU-AX implements the 78K0R CPU core with Harvard architecture, supporting 16-bit data paths and 24-bit addressing. It includes a programmable watchdog timer, low-voltage detection circuit (LVD) with 3 selectable thresholds (2.7 V, 3.3 V, 4.2 V), and on-chip debug interface compatible with QB-MINI2 emulator.
It supports multiple power-saving modes - HALT, STOP, and SNOOZE - with wake-up via external interrupt, timer, or serial interface event. The device uses SuperFlash® technology licensed from Silicon Storage Technology for reliable Flash programming and data retention over 20 years at 85°C.

Pinout & Package
UPD78F1162AGC-UEU-AX is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are defined per Renesas User's Manual U17854EJ9V0UD, Chapter 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / EVDD | Core & I/O power supply | Dual power domains: VDD powers CPU/peripherals; EVDD powers analog circuits (ADC, REGC) |
| VSS / EVSS | Ground reference | Separate digital (VSS) and analog (EVSS) grounds reduce noise coupling into ADC |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; accepts external debounced signal or power-on reset pulse |
| REGC | On-chip regulator control | Enables internal 3.3 V regulator for core when VDD = 5 V; disables regulator when VDD ≤ 3.6 V |
| AVREF | Analog reference voltage | Accepts external reference (up to VDD) or connects to internal 3.3 V regulator output for stable ADC scaling |
| P00–P06 | Port 0 bidirectional I/O | Supports NMI, INT0–INT2, and UART0 TX/RX - configurable as general-purpose or peripheral function pins |
| P10–P17 | Port 1 bidirectional I/O | Includes I²C SCL/SDA, SPI clock/MOSI/MISO, and timer array capture/compare outputs |
| P120–P124 | Port 12 analog input | Dedicated ADC input channels (AN0–AN4); share pins with P00–P04 when ADC not active |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LEAFB#30 | RL78/G13-based; 32 KB Flash, 4 KB RAM, lower max clock (24 MHz), no on-chip regulator | Targeted at cost-sensitive, lower-complexity control tasks; lacks REGC pin and analog voltage regulation | Select when BOM cost is critical and external 3.3 V LDO is already present |

FAQ
What is the maximum operating frequency of the UPD78F1162AGC-UEU-AX?
The UPD78F1162AGC-UEU-AX operates at a maximum frequency of 20 MHz using its internal high-speed oscillator or an external crystal. This frequency enables deterministic execution of real-time control algorithms with worst-case interrupt latency under 100 µs, verified per Renesas User's Manual U17854EJ9V0UD Section 3.1.1.
Does the UPD78F1162AGC-UEU-AX include an on-chip voltage regulator?
Yes, the UPD78F1162AGC-UEU-AX features an integrated voltage regulator controlled by the REGC pin. When VDD is 5 V, asserting REGC enables an internal 3.3 V supply for the core; when VDD is ≤3.6 V, the regulator is automatically disabled. This eliminates the need for an external LDO in many 5 V system designs.
How much Flash memory does the UPD78F1162AGC-UEU-AX have, and what is its endurance?
The UPD78F1162AGC-UEU-AX contains 128 KB of on-chip Flash memory implemented with SuperFlash® technology. It guarantees 100,000 write/erase cycles and 20 years of data retention at 85°C, as specified in Renesas documentation and validated per JEDEC JESD22-A117.
What debug tools are supported for the UPD78F1162AGC-UEU-AX?
The UPD78F1162AGC-UEU-AX is fully supported by Renesas' QB-MINI2 on-chip debug emulator and ID78K0R-QB integrated debugger. These tools enable real-time trace, hardware breakpoints, register inspection, and Flash programming - all accessible via the standard 10-pin debug connector defined in the UPD78F1162AGC-UEU-AX hardware manual.
Is the UPD78F1162AGC-UEU-AX pin-compatible with other 78K0R/KE3 microcontrollers?
The UPD78F1162AGC-UEU-AX shares the same 100-pin LQFP package and pinout with other members of the 78K0R/KE3 family, including UPD78F1154AGC-UEU-AX and UPD78F1146AGC-UEU-AX. Pin compatibility is confirmed in Renesas User's Manual U17854EJ9V0UD Section 1.5 and allows PCB reuse across variants with matching memory and peripheral requirements.
