Product details
Overview
UPD78F1155AGC-GAD-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 industrial control and sensor interface applications requiring deterministic real-time response.
For engineers reviewing the UPD78F1155AGC-GAD-AX datasheet, UPD78F1155AGC-GAD-AX pinout, UPD78F1155AGC-GAD-AX application, or UPD78F1155AGC-GAD-AX equivalent, key selection considerations include its 100-pin LQFP package, Flash endurance (100,000 write/erase cycles), operating temperature range (−40°C to +85°C), and support for on-chip debug via single-wire interface.
Technical Context
The UPD78F1155AGC-GAD-AX implements the 78K0R CPU core with Harvard architecture, supporting 16-bit data paths and 24-bit addressing. It integrates a programmable low-voltage detection circuit (LVD), watchdog timer (WDT) with independent clock source, and power-down modes including STOP and SNOOZE for ultra-low standby current (≤1.5 μA).
Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM capability), a 10-bit ADC with sample-and-hold and hardware trigger synchronization, and dual serial interfaces (UART and I²C) with automatic baud rate detection and clock stretching support-enabling robust communication in noisy industrial 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 |
|---|---|---|---|
| R5F100LEAFB#30 | RL78/G13-based; lower Flash (64 KB), higher active current (120 μA/MHz), no hardware ADC trigger sync | Better suited for cost-sensitive consumer appliances with simpler timing requirements | Select if BOM cost is primary constraint and ADC synchronization is not required |

FAQ
What is the maximum operating frequency of the UPD78F1155AGC-GAD-AX?
The UPD78F1155AGC-GAD-AX operates at a maximum CPU clock frequency of 20 MHz when supplied with 2.7–5.5 V. This frequency is supported across the full industrial temperature range (−40°C to +85°C) and enables deterministic instruction execution with 1.15 DMIPS/MHz throughput. The internal high-speed oscillator (HOCO) provides stable startup timing without requiring an external crystal for basic operation.
Does the UPD78F1155AGC-GAD-AX support in-system programming (ISP)?
Yes, the UPD78F1155AGC-GAD-AX supports in-system programming via its on-chip Flash memory and single-wire debug (SWD) interface. Firmware updates can be performed without removing the device from the PCB using standard Renesas tools such as the E2 emulator or PG-FP5 programmer. The UPD78F1155AGC-GAD-AX also includes read-out protection (ROP) and write protection (WP) bits to secure firmware during field deployment.
What is the ADC resolution and channel count of the UPD78F1155AGC-GAD-AX?
The UPD78F1155AGC-GAD-AX integrates a 10-bit successive approximation ADC with 16 input channels. It achieves a typical conversion time of 1.25 μs and supports internal reference voltage (2.5 V) or external reference. Hardware triggering via timer events allows precise synchronization of sampling across multiple channels - a feature confirmed in Renesas User's Manual U17854EJ9V0UD Section 3.4.2.
Is the UPD78F1155AGC-GAD-AX pin-compatible with other 78K0R/KE3 devices?
No, the UPD78F1155AGC-GAD-AX is not pin-compatible with earlier 78K0R/KE3 variants such as μPD78F1142A or μPD78F1146A due to differences in peripheral mapping and pin function allocation. While all share the same 100-pin LQFP package footprint, specific signal assignments (e.g., UART0 vs. UART1 routing, ADC channel availability) differ. Migration requires PCB layout revision and firmware adaptation per Renesas Application Note U17854EJ9V0UD Appendix A.
What quality grade is assigned to the UPD78F1155AGC-GAD-AX?
The UPD78F1155AGC-GAD-AX is classified as a "Standard" quality grade device per Renesas documentation, intended for industrial applications including computers, office equipment, communications gear, test instruments, and industrial robots. Its −40°C to +85°C operating range and qualification per JEDEC JESD22-A108 meet Standard-grade reliability requirements - confirmed in Renesas document C11531E and the UPD78F1155AGC-GAD-AX ordering information section.
