Does the UPD78F1186AGJ(R)-GAE-AX include an integrated CAN transceiver?
No, the UPD78F1186AGJ(R)-GAE-AX integrates a CAN 2.0B protocol controller but not a physical-layer transceiver. An external CAN transceiver (e.g., TJA1042 or SN65HVD230) must be used to interface with the CAN bus. The MCU provides dedicated CAN_TX and CAN_RX pins compatible with standard ISO 11898-2 signaling levels.
What package type and pin count does the UPD78F1186AGJ(R)-GAE-AX use?
The UPD78F1186AGJ(R)-GAE-AX uses a 100-pin plastic quad flat package (QFP) with 0.5 mm pitch and 14 mm × 14 mm body size. This package provides 82 general-purpose I/O pins plus dedicated power, ground, reset, and analog reference terminals, optimized for high-density industrial and automotive PCB layouts.
Is the UPD78F1186AGJ(R)-GAE-AX qualified for automotive applications?
The UPD78F1186AGJ(R)-GAE-AX is rated for industrial temperature range (−40°C to +85°C) and classified as "Standard" quality grade per Renesas documentation. While widely used in automotive body electronics, it is not AEC-Q100 qualified. For AEC-Q100-compliant alternatives, consult Renesas' RL78/F1x or RH850 families.
How many ADC channels and what resolution does the UPD78F1186AGJ(R)-GAE-AX support?
The UPD78F1186AGJ(R)-GAE-AX features a 12-bit successive-approximation ADC with 16 selectable input channels. It achieves ±1 LSB integral nonlinearity and 1.2 μs conversion time, supporting simultaneous sampling control via software trigger or timer synchronization for multi-sensor acquisition in real-time control systems.
