UPSD3434EV-40U6 highly integrated microcontroller 40MHz 288KB (288K x 8) FLASH
The UPSD3434EV-40U6 is a highly integrated microcontroller from STMicroelectronics, combining a powerful 8-bit 8032 core with a dual-bank Flash memory system and configurable programmable logic. It merges the computational reliability of a classic 8051 architecture with the flexibility of a Programmable System Device (PSD), allowing for significant system customization and peripheral integration. The device operates with a 40 MHz clock, delivering robust performance for embedded control tasks. Its integrated memory system includes 256 KB of main Flash, 32 KB of secondary Flash, and 8 KB of SRAM, supported by a Memory Management Unit (MMU) for efficient code and data handling. This makes it an ideal solution for complex applications requiring deterministic real-time control, extensive I/O management, and in-system programmability, particularly in industrial automation, automotive body control, and advanced communication modules.
At its heart lies an 8032 core (fully 8051 instruction-set compatible) enhanced with 40 MHz operation. A key architectural feature is the dual-bank Flash memory, allowing one bank to execute code while the other is being reprogrammed, enabling true In-Application Programming (IAP) and wireless firmware updates. The integrated PSD module provides 3,000 gates of programmable logic, a dedicated 16-macrocell PLD for implementing custom state machines or glue logic, and 27 configurable I/O ports. The device includes a 10-bit, 8-channel ADC, two UARTs, an I2C interface, and multiple 16-bit timers/counters.
