The PSOC™ 4 HV product family provides one-chip solutions for smart sensor automotive designs. PSOC™ 4 HV integrates high-precision programmable analog blocks and programmable digital blocks, along with a high-voltage (12V) operation. This integrates communication transceivers such as LIN/CXPI PHY and an Arm® Cortex®-M0+ CPU with embedded memory. The PSOC™ 4 HV is Automotive Electronics Council (AEC)-Q100 qualified.
PSOC™ 4 HV family sub-categories
The PSOC™ 4 HV product family is categorized into sub-family:
- PSOC™ 4 HV Precision Analog (PA) is a fully-integrated programmable embedded system for battery monitoring and management. This system features an Arm® Cortex®-M0+ processor and programmable and reconfigurable analog with high-precision sigma-delta ADC, digital blocks, and high-voltage sub-system included LDO and LIN transceivers
- PSOC™ HV Mixed Signal (MS) is a fully integrated programmable embedded system for several automotive HMI, body, and power-train applications. This system features an Arm® Cortex®-M0+ processor with programmable and reconfigurable analog and digital blocks with 5th generation multi-sense converter (MSC) block supporting capacitive sensing (CAPSENSE™) and a high-voltage sub-system including LDO and a LIN/CXPI transceiver
PSOC™ 4 HV PA
key features
- One-chip solution for smart sensors, integrating analog front-end, MCU, and connectivity, that saves board space
- High-precision analog performance for high-accuracy applications such as current-sensing
- Safe smart sensor and HMI designs with integrated functional safety features
- Connects directly to a 12-V battery supply and to the LIN network
- Total system solution (hardware, software, and collaterals)
- Small packages: 32-pin, 48-pin, 56-pin, and 64-pin wettable flank QFNs
Target applications
- PSOC™ 4 HVPA:
