STMicroelectronics 

1 - INTRODUCTION

ST10F269

1 - INTRODUCTION

The ST10F269 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 is processed in 0.35µm CMOS

technology. The MCU core and the logic is

supplied with a 5V to 3.3V on chip voltage

regulator on PQFP144 devices (or 5V to 2.7V on

TQFP144 devices). The part is supplied with a

single 5V supply and I/Os work at 5V.

The device 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.

– 128-KByte Flash Option

– Two dedicated pins (DC1 and DC2) on the

144-pin package are used for decoupling the

internally generated 3.3V (or 2.7V on TQFP144

devices) 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 ≥ 330

nF).

– The A/D Converter characteristics are different

from previous ST10 derivatives ones. Refer to

Section 21.3.1 -.

– The AC and DC parameters are adapted to the

40MHz maximum CPU frequency on PQFP144

devices (32MHz on TQFP144 devices). The

characterization is performed with CL = 50pF

max on output pins. Refer to Section 21.3 -.

– 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 -.

– 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.
