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 UPD78F1162GC(S)-UEU-AX datasheet, UPD78F1162GC(S)-UEU-AX pinout, UPD78F1162GC(S)-UEU-AX application, or UPD78F1162GC(S)-UEU-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), and support for on-chip debug via single-wire interface - all critical for cost-sensitive, long-lifecycle industrial firmware deployments.

Technical Context

The UPD78F1162GC(S)-UEU-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a 12-bit successive-approximation ADC with sample-and-hold and programmable conversion timing, plus dual UART modules supporting asynchronous communication with selectable baud rates.

Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM functions), an I²C bus interface compliant with SMBus v2.0, and a watchdog timer with independent clock source. The device supports low-power modes (HALT, STOP) with wake-up via external interrupt or peripheral event.

FAQ

What is the maximum operating frequency of the UPD78F1162GC(S)-UEU-AX?

The UPD78F1162GC(S)-UEU-AX supports a maximum system clock frequency of 20 MHz when using the on-chip PLL with an external crystal or ceramic resonator. Without PLL, the maximum frequency is 16 MHz using the main oscillator. This timing capability enables real-time processing of ADC conversions and PWM updates within tight industrial control loops - essential for stable operation of the UPD78F1162GC(S)-UEU-AX in motor drive applications.

Does the UPD78F1162GC(S)-UEU-AX support in-system programming (ISP)?

Yes, the UPD78F1162GC(S)-UEU-AX supports in-system programming via its built-in UART or I²C interface using the on-chip self-programming function. This allows firmware updates without removing the device from the PCB - a key advantage for field-deployed equipment. The UPD78F1162GC(S)-UEU-AX requires no external programmer for basic reprogramming, though Renesas' PG-FP5 is recommended for high-volume production programming and security key provisioning.

What is the Flash memory endurance specification for the UPD78F1162GC(S)-UEU-AX?

The UPD78F1162GC(S)-UEU-AX guarantees 100,000 write/erase cycles for its on-chip Flash memory, with data retention exceeding 10 years at +85°C. This endurance rating is validated under standard industrial test conditions and applies to all Flash sectors - including those used for EEPROM emulation. For applications requiring frequent parameter logging, the UPD78F1162GC(S)-UEU-AX's Flash wear-leveling routines (implemented in Renesas' Self Programming Library) help distribute writes and extend effective lifetime.

Is the UPD78F1162GC(S)-UEU-AX pin-compatible with other members of the 78K0R/KG3 family?

No, the UPD78F1162GC(S)-UEU-AX is not fully pin-compatible with other 78K0R/KG3 variants such as the UPD78F1163 or UPD78F1164 - differences exist in peripheral mapping, I/O multiplexing, and power pin allocation. While the 100-pin LQFP package footprint is shared, signal assignments on ports P12–P15 and analog reference pins vary across the family. Engineers must consult the specific pin function table for the UPD78F1162GC(S)-UEU-AX to avoid functional mismatches during board design or migration.

What debug interface does the UPD78F1162GC(S)-UEU-AX support?

The UPD78F1162GC(S)-UEU-AX supports single-wire on-chip debugging (SWD) via the dedicated BKGD pin, enabling full visibility into CPU registers, memory, and peripheral states during development. This interface is supported by Renesas' E1/E20 emulators and third-party tools compliant with the 78K0R debug specification. Unlike JTAG, SWD uses only one signal line plus ground - simplifying PCB routing while retaining breakpoint, step-through, and memory dump capabilities for the UPD78F1162GC(S)-UEU-AX.
