PSoC™ 4 HVPA-144K

Based on 32-bit Arm® Cortex®-M0+

General description

PSoC™ 4 High Voltage Precision Analog (HVPA)-144K is a fully integrated programmable embedded system for

lead acid battery monitoring and management. The system features an Arm® Cortex® M0+ processor and

programmable and reconfigurable analog and digital blocks.

Features

• Automotive Electronics Council (AEC) AEC-Q100 qualified

• 32-bit MCU subsystem

- 24- or 48-MHz Arm® Cortex® M0+ CPU with DMA controller

- Up to 128 KB of code flash with ECC

- Up to 8 KB of data flash with ECC

- Up to 8 KB of SRAM with ECC

- 1 KB of supervisory flash (SFlash) available for storing constants

• Precision analog

- Two precision ΔΣ ADCs (16-20+ bits)

- Current channel with automatic gain

- Voltage channel with HV input divider

- Temperature and diagnostic channels

- Supports both internal and external temperature sensing

- Digital filtering, accumulators, and threshold comparisons on all channels

• High-voltage subsystem

- Operates directly off 12-V/24-V battery (tolerates up to 42 V)

- Integrated LIN transceiver

- ADC input voltage divider

• Functional safety for ASIL-B

- Developed according to the development process of ISO 26262 for ASIL B as a Safety Element out of Context

(acc. ISO26262-10:2018E, clause 9)

- Memory protection unit (MPU)

- Window watchdog timer (WDT) with challenge-response functionality

- Supply monitoring; detection of overvoltage and brownout events for 3.3-V and 1.8-V supplies

- Hardware error correction (SECDED ECC) on all safety-critical memories (SRAM, flash)

- Analog diagnostics (backup reference voltage, redundancy in voltage, current, and temperature measure-

ment paths)

• Timing and pulse-width modulation

- Four 16-bit timer/counter/pulse-width modulator (TCPWM) blocks

- Center-aligned, Edge, and pseudo-random modes

- Quadrature decoder

• Clock sources

- ±2% up to 49.152-MHz internal main oscillator (IMO)

- ±1% 2-MHz high-precision oscillator (HPOSC)

- ±5% or ±7% 32-kHz precision internal low-power oscillator (PILO) based on the part number

- ±1% or ±1.5% accuracy on IMO and PILO when software calibrated to the HPOSC based on the part number

- 40-kHz internal low-speed oscillator (ILO)
