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.
