FAQ
What is the maximum operating frequency of the UPD78F1168AGC-UEU-AX?
The UPD78F1168AGC-UEU-AX operates at a maximum CPU clock frequency of 20 MHz using its on-chip high-speed oscillator or external crystal input. This frequency is supported across the full −40°C to +85°C temperature range and 2.7–5.5 V supply voltage, with timing verified per the device's electrical specifications in the official Renesas datasheet U17894EJ9V0UD.
Does the UPD78F1168AGC-UEU-AX include a built-in CAN transceiver?
No, the UPD78F1168AGC-UEU-AX integrates a CAN 2.0B protocol controller only - it requires an external CAN physical-layer transceiver (e.g., SN65HVD230 or TJA1042) for bus connection. The MCU provides dedicated CAN_TX and CAN_RX pins (mapped to P00/P01) that interface directly with the transceiver's TXD/RXD lines.
What is the Flash memory endurance specification for the UPD78F1168AGC-UEU-AX?
The UPD78F1168AGC-UEU-AX uses SuperFlash® technology with guaranteed endurance of 100,000 write/erase cycles and data retention of 20 years at +85°C. These values are specified in Renesas' official documentation and validated under JEDEC JESD22-A117 conditions, applying to the full 128 KB on-chip Flash memory array used by UPD78F1168AGC-UEU-AX.
Is the UPD78F1168AGC-UEU-AX qualified for automotive applications?
Yes, the UPD78F1168AGC-UEU-AX is qualified per AEC-Q100 Grade 2 (−40°C to +105°C ambient, though rated for −40°C to +85°C operation), and classified as "Standard" quality grade per Renesas' internal categorization - explicitly approved for automotive body electronics, chassis systems, and industrial control where functional safety ASIL levels are not required.
How many ADC channels does the UPD78F1168AGC-UEU-AX support, and what is their resolution?
The UPD78F1168AGC-UEU-AX features a single 12-bit successive-approximation ADC with 8 input channels (AN0–AN7), configurable for single-ended operation. Conversion time is 1.2 μs typical at 20 MHz CPU clock, and inputs are routed through Port 1 pins (P10–P17), with dedicated AVREF0/AVREF1 reference voltage inputs and AVSS analog ground separation.
