The UPD78F1164AGC(S)-UEU-AX supports a maximum CPU clock frequency of 20 MHz using its on-chip PLL, with base system clock options including external crystal (1–20 MHz), ceramic resonator, or internal high-speed oscillator. At 20 MHz, the instruction execution time is 50 ns per cycle for most instructions, enabling real-time response in motor control and CAN messaging applications. The UPD78F1164AGC(S)-UEU-AX maintains timing integrity across its full −40°C to +85°C operating range.
Does the UPD78F1164AGC(S)-UEU-AX include an integrated CAN transceiver?
No, the UPD78F1164AGC(S)-UEU-AX integrates only the CAN protocol controller (CAN 2.0B compliant), not the physical layer transceiver. External CAN transceivers such as the TJA1042 or SN65HVD230 must be used to drive the CANH/CANL bus lines. The UPD78F1164AGC(S)-UEU-AX provides dedicated P40 (CAN0_TX) and P41 (CAN0_RX) pins with configurable slew rate and output drive strength to interface reliably with standard ISO 11898-2 transceivers.
What debug interface does the UPD78F1164AGC(S)-UEU-AX support?
The UPD78F1164AGC(S)-UEU-AX features the FINE (Flash Internal Non-intrusive Emulator) debug interface, a single-pin serial interface supporting non-intrusive flash programming, real-time variable monitoring, and breakpoint-based debugging. It is compatible with Renesas' E1 emulator and QB-MINI2 debug tools. Unlike JTAG, FINE requires no additional pins beyond the dedicated FINE pin and ground, simplifying PCB layout while maintaining full visibility into CPU registers and memory during development of the UPD78F1164AGC(S)-UEU-AX.
Is the UPD78F1164AGC(S)-UEU-AX qualified for automotive applications?
Yes, the UPD78F1164AGC(S)-UEU-AX is rated for operation from −40°C to +85°C and conforms to AEC-Q100 stress test qualifications for Grade 3 components. Its integrated CAN 2.0B controller, fail-safe reset circuitry, and robust ESD protection (±4 kV HBM) make it suitable for automotive body electronics applications such as door modules, seat controllers, and lighting ECUs. The UPD78F1164AGC(S)-UEU-AX is classified as "Standard" quality grade per Renesas documentation, appropriate for non-safety-critical automotive systems.
How many ADC channels does the UPD78F1164AGC(S)-UEU-AX support?
The UPD78F1164AGC(S)-UEU-AX includes a 12-bit successive-approximation ADC with 16 selectable input channels (AN0–AN15), mapped across ports P14, P15, and dedicated analog pins. It supports single-ended and pseudo-differential conversion modes, programmable sampling time, and hardware-triggered scan sequences. The ADC achieves ±1 LSB integral nonlinearity and 1.2 μs conversion time, enabling accurate voltage, current, and temperature measurements in real-time control loops implemented on the UPD78F1164AGC(S)-UEU-AX.
