18 / 346 page ![]() Obsolete Product(s) - Obsolete Product(s) Description ST10F296E 18/346 ● The ADC is not fully compatible with the ST10F280 (timing and programming model). The formula for the convertion time is still valid, while the sampling phase programming model is different. ● The external memory bus potential limitations on maximum speed and maximum capacitance load are under evaluation and may be introduced: ST10F296E will probably not be able to address an external memory at 64 MHz with 0 wait states. ● The XPERCON register bit mapping has been modified according to new peripheral implementation (which is not fully compatible with ST10F280). ● The bondout chip for emulation (ST10R201) cannot achieve more than 50 MHz at room temperature (so, no real-time emulation is possible at maximum speed). ● Input section characteristics are different. The threshold programmability is extended to all port pins (additional XPICON register); it is possible to select standard TTL (with up to 400 mV of hysteresis) and standard CMOS (with up to 750 mV of hysteresis). ● Output transition is not programmable. ● An RTC module has been added. ● The CAN module has been enhanced: ST10F296E implements two C-CAN modules, so the programming model is slightly different. The possibility to map both CAN modules simultaneously has been added (on P4.5/P4.6). ● The on-chip main oscillator input frequency range has been reshaped, reducing it from 1-25 MHz to 4-12 MHz. This is a high performance oscillator amplifier, that provides a very high negative resistance and wide oscillation amplitude. When this on-chip amplifier is used as a reference for the RTC module, the power-down consumption is dominated by the consumption of the oscillator amplifier itself. A metal option is added to offer a low power oscillator amplifier working in the range 4-8 MHz which allows a power consumption reduction when the RTC is running in power-down mode using the on-chip main oscillator clock as a reference. ● The possibility to reprogram the internal XBus chip select window characteristics (XRAM2 and XFlash address window) has been added.
