ST7265x
INTRODUCTION (Cont’d)
In addition to the peripherals for USB full speed
data transfer, the ST7265x includes all the neces-
sary features for stand-alone applications with
FLASH mass storage.
– Low voltage reset ensuring proper power-on or
power-off of the device (not on all products)
– Digital Watchdog
– 16-bit Timer with 2 output compare functions (not
on all products - see device summary).
– Two 10-bit PWM outputs (not on all products -
see device summary)
– Serial Peripheral interface (not on all products -
see device summary)
– Fast I2C Single Master interface (not on all prod-
ucts - see device summary)
– 8-bit Analog-to-Digital converter (ADC) with 8
multiplexed analog inputs (not on all products -
see device summary)
The ST72F65x are the Flash versions of the
ST7265x in a TQFP64 package.
The ST7265x are the ROM versions in a TQFP64
package.
