ST10F269-T3

Note: 1. Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. During overload conditions (V_IN > V_DD or V_IN < V_SS ) the voltage on pins with respect to ground (VSS ) must not exceed the values defined by the Absolute Maximum Ratings.

The ST10F269-T3 is a derivative of the STMicroelectronics ST10 family of 16-bit single-chip CMOS microcontrollers. It combines high CPU performance (up to 20 million instructions per second) with high peripheral functionality and enhanced I/O-capabilities. It also provides on-chip high-speed single voltage Flash memory, on-chip high-speed RAM, and clock generation via PLL.

ST10F269-T3 is processed in 0.35mm CMOS technology. The MCU core and the logic is supplied with a 5V to 2.7V on chip voltage regulator. The part is supplied with a single 5V supply and I/Os work at 5V.

The ST10F269-T3 is upward compatible with the ST10F168 device, with the following set of differences:
The Multiply/Accumulate unit is available as standard. This MAC unit adds powerful DSP functions to the ST10 architecture, but maintains full compatibility for existing code.
Flash control interface is now based on STMicroelectronics third generation of stand-alone Flash memories, with an embedded Erase/Program Controller. This completely frees up the CPU during programming or erasing the Flash.
Two dedicated pins (DC1 and DC2) on the

ST10F269-T3 package are used for decoupling the internally generated 2.7V core logic supply. Do not connect these two pins to 5.0V external supply. Instead, these pins should be connected to a decoupling capacitor (ceramic type, value ³ 330 nF).
The A/D Converter characteristics are different from previous ST10 derivatives ones. Refer to Section 21.3.1 - A/D Converter Characteristics.
The AC and DC parameters are adapted to the 32MHz maximum CPU frequency. The characterization is performed with CL = 50pF max on output pins. Refer to Section 21.3 DC Characteristics.
In order to reduce EMC, the rise/fall time and the sink/source capability of the drivers of the I/O pads are programmable. Refer to Section 12.2 I/ O's Special Features.
The Real Time Clock functionality is added.
The external interrupt sources can be selected with the EXISEL register.
The reset source is identified by a dedicated status bit in the WDTCON register.
