2 / 4 page Ordering information ST10F276, ST10F273 2/4 1 Ordering information Table 1. Ordering information 1.1 ST10F276/ST10F273 compatibility The only differences between ST10F276 and ST10F273 devices are the embedded Flash and RAM resources: Flash Memory: ST10F276 includes 832 Kbytes of on-chip single voltage Flash divided into four banks allowing for Read-While-Write Operation. Two banks are mapped on the internal 32- bit bus (IFLASH) and the two others are mapped on 16-bit XBUS (XFLASH). ● In ST10F273 devices the XFLASH banks are not available. As a consequence, only the standard ST10 bootstrap mode can be used (no Alternate Boot Mode). RAM: The ST10F273 includes 68 Kbytes of on-chip RAM, divided into 3 blocks: 2 Kbytes IRAM dual-ported RAM block, 2 Kbytes XRAM1 extension RAM block and 64KBytes XRAM2 extension RAM block. ● In ST10F273 devices the XRAM2 on-chip extension RAM block is reduced to 32 Kbytes. Note: There is no built-in feature to allow software to detect if the device is an F276 or an F273. The missing memory in the ST10F273 can be seen as regular memory. If you wish make two assemblies of the same PCB with the ST10F276 and ST10F276, we advise to put a pull-up resistor on an I/O to differentiate the two configurations by software. Table 2.
