Product details
Overview
CYSHM35926P-L068LTIT from Infineon Technologies (acquired Cypress Semiconductor) is a programmable embedded system controller based on the ARM® Cortex®-M0 CPU, integrating digital programmable logic (8 UDBs), 4 opamps with comparator mode, 2 low-power comparators, 4 current DACs, 8 TCPWM blocks, and 4 reconfigurable serial communication blocks (I²C/SPI/UART). It operates from 1.71 V to 5.5 V and supports Deep Sleep mode at 20 nA with GPIO wakeup - deployed in industrial HMI and automotive body control modules requiring field-reconfigurable analog/digital signal conditioning.
For engineers reviewing the CYSHM35926P-L068LTIT datasheet, CYSHM35926P-L068LTIT pinout, CYSHM35926P-L068LTIT application, or CYSHM35926P-L068LTIT equivalent, key selection criteria include its 68-pin QFN package, 48 MHz CPU clock, 256 kB flash + 32 kB SRAM, dual CAN interfaces, USB Full-Speed device support, and programmable analog routing for sensor interface tuning without hardware change.
Technical Context
The device implements a multi-layer AHB-Lite interconnect architecture with dedicated analog clock leading digital clocks to minimize noise coupling during ADC sampling. Its programmable analog subsystem includes four opamps configurable as buffers, amplifiers, or comparators - all operable in Deep Sleep with sub-μA quiescent current and flexible pin-to-block routing via the I/O Subsystem Matrix.
Digital programmability is realized through eight Universal Digital Blocks (UDBs), each with an 8-bit data path and 8 macrocells, supporting user-defined state machines or Verilog-synthesized logic. The SWD debug interface enables full on-chip debugging without external pods, and device security features include flash protection, debug disable via firmware, and permanent interface lockdown to prevent malicious reprogramming.

FAQ
What development tools are required to program CYSHM35926P-L068LTIT?
The PSoC Creator IDE is mandatory for schematic-based design entry, automatic analog/digital routing, and component API generation. ARM GCC toolchain integration is supported, and debug uses standard Serial Wire Debug (SWD) with CMSIS-DAP or Segger J-Link probes - no proprietary hardware debugger required.
Does CYSHM35926P-L068LTIT support functional safety certification?
While not pre-certified to ISO 26262 ASIL-B or IEC 61508 SIL-2, the device includes safety-relevant features: lockable flash, ECC on SRAM, CRC engines, watchdog timers with independent clock source (ILO), and fail-safe GPIO configurations - enabling customer-led safety qualification for automotive or industrial systems.
Can the opamps operate while the CPU is in Deep Sleep mode?
Yes - all four opamps and two low-power comparators remain fully operational in Deep Sleep mode with typical quiescent current below 1 µA per opamp. Their outputs can trigger interrupts or DMA transfers without waking the CPU, enabling continuous sensor monitoring at microamp-level power.
Is external memory expansion supported?
Yes - the device supports secure off-chip memory expansion via the Serial Memory Interface (SMIF), allowing connection to external NOR/NAND flash or PSRAM. Encryption keys are stored in protected flash, and SMIF transactions can be authenticated to prevent unauthorized memory access.
