Product details
Overview
CY8C3446PVE-102 from Infineon Technologies (acquired Cypress Semiconductor) is an AEC-Q100 qualified automotive-grade PSoC® 3 programmable system-on-chip integrating an 8051 CPU core, 64 KB flash, 8 KB SRAM, 2 KB EEPROM, 24-channel DMA, full CAN 2.0b interface (16 Rx/8 Tx), USB 2.0 Full-Speed peripheral, and configurable analog/digital peripherals - deployed in engine control units, body electronics, and battery management systems.
For engineers reviewing the CY8C3446PVE-102 datasheet, CY8C3446PVE-102 pinout, CY8C3446PVE-102 application, or CY8C3446PVE-102 equivalent, key selection criteria include AEC-Q100 Grade 2 qualification (–40 °C to +105 °C), 50 MHz max CPU speed, 12-bit delta-sigma ADC with 192 ksps and 66 dB SINAD, dual opamps with 25 mA drive, and 62 GPIOs with CapSense® and LCD direct-drive capability.
Technical Context
The CY8C3446PVE-102 implements a single-cycle 8051 microcontroller core with hardware multiply/divide, supported by a multilayer AHB bus for high-bandwidth DMA transfers across 24 channels. Its digital subsystem centers on 24 Universal Digital Blocks (UDBs), each combining PLD logic and state machines to implement custom peripherals including LIN, CRC, quadrature decoders, and programmable PWMs.
Analog functionality is anchored by a 1.024 V ±0.1% internal voltage reference, enabling a configurable delta-sigma ADC (8–12-bit, up to 192 ksps), four comparators (95 ns response), two uncommitted opamps (25 mA output), and two SC/CT blocks supporting PGA, TIA, and mixer configurations - all routable to any of 62 GPIOs via dedicated analog interconnect.

FAQ
Is CY8C3446PVE-102 pin-compatible with other CY8C34 devices?
Yes - CY8C3446PVE-102 uses the 100-pin TQFP package shared across CY8C34xx-10x variants. Pin functions (e.g., USB_DP/DM, CAN_TX/RX, XRES) are consistent within the CY8C3446 subfamily. However, peripheral enablement (e.g., USB, CAN) depends on specific part number suffixes and must be verified against the Ordering Information table in datasheet 001-57331 Rev. *G.
Does CY8C3446PVE-102 support bootloader updates over CAN?
Yes - the device supports field firmware updates via its integrated CAN 2.0b peripheral using the PSoC Creator Bootloader Component. The bootloader can be configured to accept Intel HEX or binary images over CAN frames, with checksum validation and rollback protection enabled through flash security features.
What is the maximum operating temperature for CY8C3446PVE-102?
CY8C3446PVE-102 is rated for –40 °C to +105 °C ambient temperature and is qualified to AEC-Q100 Grade 2. This rating applies to continuous operation with full specification compliance; derating is not required within this range per datasheet Section 11.2 Device Level Specifications.
Can the internal opamps drive a 50 Ω load?
No - the two uncommitted opamps are specified for 25 mA continuous sink/source into resistive loads, corresponding to ≥200 Ω minimum at 5 V. Driving a 50 Ω load would exceed safe operating area limits and cause thermal shutdown or parametric shift; external buffer amplifiers are required for such low-impedance applications.
