PSoC™ 4 HV PA subcategories
The PSoC™ 4 High Voltage (HV) Precision Analog (PA) is a cutting-edge device that has been fully integrated into a programmable embedded system, providing outstanding battery monitoring and management capabilities. This device boasts an Arm® Cortex® M0+ processor, which ensures precise and accurate battery monitoring. One of the greatest features of this device is its programmable and reconfigurable analog and digital blocks that provide flexibility and versatility.
The PSoC™ 4 HV PA is an excellent choice for automotive applications, as it is Automotive Electronics Council (AEC)-Q100 qualified. This device can operate directly from a 12-V/24-V battery and can tolerate up to 42 V, making it an ideal solution for various automotive applications. It also features integrated LIN transceiver and ADC input voltage divider.
With up to 128 KB of code flash with ECC, up to 8 KB of data flash with ECC, and up to 8 KB of SRAM with ECC, the PSoC™ 4 HV PA provides ample space for storing data and constants. Additionally, 1 KB of Supervisory Flash (SFlash) is available for storing constants.
The Precision Analog subsystem of PSoC™ 4 HV PA is equipped with two Precision ΔΣ ADCs (16-20+ bits) and current and voltage channels with automatic gain. The voltage channel comes with an HV input divider, which helps in accurate voltage measurement. The temperature and diagnostic channels support both internal and external temperature sensing. Digital filtering, accumulators, and threshold comparisons are provided on all channels.
