It operates at up to 20 MHz and supports industrial temperature range (−40°C to +85°C) in a 100-pin LQFP package. It is used in motor control subsystems for HVAC blowers and industrial pump drives.

For engineers reviewing the UPD78F1167AGF(S)-GAS-AX datasheet, UPD78F1167AGF(S)-GAS-AX pinout, UPD78F1167AGF(S)-GAS-AX application, or UPD78F1167AGF(S)-GAS-AX equivalent, key selection criteria include CAN bus integration, Flash endurance (100k write/erase cycles), ADC resolution and sampling rate, TAU timer flexibility for PWM generation, and qualification for industrial-grade operation per Renesas "Standard" quality grade.

Technical Context

The UPD78F1167AGF(S)-GAS-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 series. It integrates a dedicated CAN controller supporting both standard and extended frames, with programmable bit timing and message object buffers.

Its peripheral set includes dual 16-bit timer arrays (TAU0/TAU1) capable of complementary PWM output with dead-time insertion, a 12-bit successive-approximation ADC with hardware-triggered sampling synchronized to timer events, and a voltage regulator (REGC pin) enabling single-supply operation from 3.0–5.5 V.

The UPD78F1167AGF(S)-GAS-AX features 128 KB of on-chip Flash memory rated for 100,000 write/erase cycles per block, with data retention guaranteed for 20 years at +85°C. This endurance enables robust in-field firmware updates and parameter storage without external EEPROM. The UPD78F1167AGF(S)-GAS-AX supports in-application programming (IAP) via UART or CAN, allowing safe background updates while maintaining real-time control tasks.

How many ADC channels does the UPD78F1167AGF(S)-GAS-AX support, and what is its resolution?

The UPD78F1167AGF(S)-GAS-AX includes a single 12-bit successive-approximation ADC with 8 configurable input channels (AN0–AN7). Conversion time is 1.2 μs at maximum speed, and sampling can be triggered by software, timer overflow, or compare match events. The ADC supports separate analog reference pins (AVREF0/AVREF1) for flexible ratiometric or absolute measurements. This capability is documented in the "Analog Functions" chapter of the UPD78F1167AGF(S)-GAS-AX User's Manual U17894EJ9V0UD.
