It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets industrial control and sensor interface applications.

For engineers reviewing the UPD78F1168AGF(S)-GAS-AX datasheet, UPD78F1168AGF(S)-GAS-AX pinout, UPD78F1168AGF(S)-GAS-AX application, or UPD78F1168AGF(S)-GAS-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 confirmed for this specific GF(S) package variant.

Technical Context

The UPD78F1168AGF(S)-GAS-AX implements the 78K0R CPU core with 16-bit architecture, supporting both standard and expanded instruction sets. It integrates a 10-bit successive-approximation ADC with programmable sampling time and conversion trigger sources including timer overflows and external pins.

Peripheral configuration includes three 16-bit timer arrays (each with capture/compare, PWM, and interval timer modes), two serial interfaces (UART and I²C), and a watchdog timer with independent clock source. All peripherals are memory-mapped and controlled via dedicated SFRs with interrupt capability on status change.

FAQ

What is the maximum operating frequency of the UPD78F1168AGF(S)-GAS-AX?

The UPD78F1168AGF(S)-GAS-AX supports a maximum system clock frequency of 20 MHz when using the on-chip PLL; without PLL, the maximum is 16 MHz from external crystal or ceramic resonator. This timing specification is validated across the full −40°C to +85°C temperature range and 2.7–5.5 V supply voltage, ensuring deterministic execution in industrial environments.

Does the UPD78F1168AGF(S)-GAS-AX include an internal voltage regulator?

Yes, the UPD78F1168AGF(S)-GAS-AX integrates an internal voltage regulator controlled by the REGC pin. When enabled, it supplies regulated core voltage (1.8 V) from the main VDD supply (2.7–5.5 V), reducing external component count. The REGC pin must be externally decoupled with a 100 nF capacitor to ensure stable regulation - a requirement explicitly defined in Renesas User's Manual U17894EJ9V0UD.

How many ADC channels does the UPD78F1168AGF(S)-GAS-AX support, and what is its resolution?

The UPD78F1168AGF(S)-GAS-AX features a 10-bit successive-approximation ADC with 16 input channels (AN0–AN15), mapped across Ports 1 and 4. Conversion time is typically 1.2 μs, and the ADC supports hardware triggering from multiple sources including timer overflows and external pins - enabling precise synchronized sampling without CPU intervention.

Is the UPD78F1168AGF(S)-GAS-AX pin-compatible with other members of the 78K0R/KG3 family?

The UPD78F1168AGF(S)-GAS-AX shares the same 100-pin LQFP package and pinout with other 78K0R/KG3 devices in the GF(S) variant group (e.g., UPD78F1167AGF(S)-GAS-AX), but is not pin-compatible with earlier μPD78F1168 or non-A variants due to differences in peripheral mapping and register layout. Pin compatibility is strictly limited to expanded-specification A-grade parts in identical package codes.

What debug interface does the UPD78F1168AGF(S)-GAS-AX support?

The UPD78F1168AGF(S)-GAS-AX supports single-wire on-chip debug (OCDS) compliant with Renesas QB-MINI2 and ID78K0R-QB emulators. This interface provides full breakpoint, step-execution, and memory/register access capabilities without requiring additional pins beyond RESET and TCK - preserving all I/O for application use while enabling robust firmware development and field diagnostics.
