Product details
Overview
CY8C4147LCE-HV403T from Infineon is a 32-bit Arm® Cortex®-M0+ MCU with integrated high-voltage precision analog subsystem, designed for lead-acid battery monitoring in automotive and industrial systems. It features dual 16–20+ bit ΔΣ ADCs (current/voltage/temperature/diagnostic), operates directly from 12 V/24 V battery (up to 42 V), includes LIN 2.2A-compliant transceiver, and supports ASIL B hardware metrics per ISO 26262.
For engineers reviewing the CY8C4147LCE-HV403T datasheet, CY8C4147LCE-HV403T pinout, CY8C4147LCE-HV403T application, or CY8C4147LCE-HV403T equivalent, key selection criteria include HV battery input tolerance, dual-precision ΔΣ ADC channel architecture, LIN protocol compliance, AEC-Q100 qualification, and functional safety support for ASIL B/B-C system integration.
Technical Context
The device implements a dedicated high-voltage analog acquisition path with internal HV input divider for battery voltage sensing and automatic gain control for current measurement-enabling direct connection to shunt resistors without external amplification. Its PACSS (Precision Analog Channel Subsystem) provides independent sequenced sampling across four channels with digital filtering, accumulators, and threshold-triggered interrupts.
Functional safety is embedded at silicon level: SECDED ECC protects all SRAM, flash, and SFlash; MPU enforces memory access boundaries; windowed WDT uses challenge-response; and analog diagnostics include redundant reference voltage and cross-channel measurement validation for voltage, current, and temperature paths.

FAQ
Does CY8C4147LCE-HV403T support external crystal oscillators?
No. The device relies exclusively on internal oscillators: 49.152 MHz IMO, 2 MHz HPOSC, 32 kHz PILO, and 40 kHz ILO. No external crystal or oscillator input pins are provided - clock stability is maintained through software calibration of IMO/PILO against HPOSC, achieving ±1% accuracy.
What is the maximum measurable battery voltage using the integrated HV divider?
The internal HV input divider scales down up to 42 V battery voltage to a safe range for the voltage-channel ADC. With a fixed 13.5:1 division ratio and 3.3 V reference, the effective full-scale input is 42 V - verified in Absolute Maximum Ratings (Section 4.1) and Electrical Specifications (Section 4.3.5).
Can the current-sense ADC channel operate with zero external components?
Yes. The current channel accepts differential inputs (ISENSE_P/N) directly from a shunt resistor and includes programmable gain stages (1× to 128×) and auto-ranging logic. No external op-amps, filters, or gain-setting resistors are required for typical 0–200 A measurement ranges.
Is SWD debug supported in all power modes?
SWD is fully operational in Active and Sleep modes. In DeepSleep mode, SWD remains accessible only if the debug enable bit is set in SFlash and the XRES pin is asserted - otherwise, debug access is disabled to prevent unintended wake-up or security exposure during ultra-low-power operation.
