UCV-02XA module is a central processing unit organized around a P51XAS3 type microcontroler (a Philips Semiconductors product)/ PXAS30KFA (NXP) as last version, providing far superior resources compared to UCV-01, UCV-02, and UCV-03MON. The resource enhancement is mainlu due to its microcontroler type.

The overall dimensions of UCV-02XA are reduced by 30% compared to UCV-01XA.

The 16-bit XA microcontrolers used are powerful enough to fulfill the enhanced performance application requirements while maintaining low costs in the context of series application market.

XA architecture performances allows 80C51 bit-operations while providing support for multitasking operating systems and high-level programming languages cuch as C. XA architecture speed is 10 to 100 times better than the speed of 80C51 , thus offering an easy solution for enhanced performance control applications.

XA architecture technical features:

80C51 compatibility;
16-bit CPU, with 24-bit space for addressing and program;
8 CPU registers of 16 bits, each featuring all arithmetic and logic operations with the same performance as memory pointers; direct memory operations;
both 8-bit and 16-bit processing, for all arithmetic and logic operations;
complex instruction set including bitwise operations, fast 16x16 multiplying and 32/16 division;
high-level language designed instruction set;
multi-tasking real-time executives including up to 32 interrupt arrays, 16 "software traps" segmented data memory, and specific context-changing registers;
XA low consumption provides "power-down" and "idle" operating modes.

UCV-02XA is equipped with XA-S3 microcontroler, wich integrates several periphericals, featuring A/D converter, timers/counters, watchdog, programable counters (PCA), I2C interface, dual UART, and various input/output ports.

UCV-02XA is suitable to high complexity applications, providing important hardware resources:

XA-S3 microcontroler, 11.0952 MHz ferquency (or various);
64 KB program memory;
system SRAM: 64 kB, extendable to 16 MB;
2 KB EEPROM de 2 KB serially connected on I2C bus;
TIMEKEEPER and NVSRAM 8 KB socket ;
bidirectional 16-bit external bus, for easy input/output port interfacing, including alphanumerical or graphical LCD module compatibility
16MB memory extension bus for SRAM or FLASH;
UART 1, 2 ( d2 serial interfaces) available in connectors;
processor ports of main interest available in connectors;
5V supply voltage.

UCV-02XA is an open structure, ensuring enhanced application versatility for both acquisition and local data processing, while communicating to other modules of implemented systems.
