This document presents the process of porting an application from ST10F269Zx to ST10F273Z4, including modified and new functionalities.
The document highlights functional differences, modified features, new functionalities, and register changes when adapting an existing application based on the ST10F269Zx to the ST10F273Z4. It covers impacts on pinout, XRAM size, Flash EEPROM organization, ADC conversion timing, real-time clock, CAN modules, ports, PLL, and various registers.
| Flash size (ST10F273Z4) | 512 Kbytes |
|---|---|
| Flash organization (ST10F273Z4) | 10 blocks |
| Programming voltage | 5 volts |
| Program/Erase cycles | 100000 |
| XRAM size (ST10F273Z4) | 34 Kbytes |
To highlight the differences between the ST10F269Zx and the ST10F27324 devices for designers adapting applications.
In the new device, pin 17 is a Vpp pin instead of requiring a decoupling capacitor.
The ST10F269Zx has 10 Kbytes of extension RAM whereas the ST10F273Z4 has 34 Kbytes.
