Introduction
ST10F276E
● Embedded memory size has been significantly increased (both Flash and RAM).
● PLL multiplication factors have been adapted to new frequency range.
A/D Converter is not fully compatible versus ST10F269 (timing and programming
model). Formula for the conversion time is still valid, while the sampling phase
programming model is different.
Besides, additional 8 channels are available on P1L pins as alternate function: the
accuracy reachable with these extra channels is reduced with respect to the standard
Port5 channels.
● External Memory bus potential limitations on maximum speed and maximum
capacitance load could be introduced (under evaluation): ST10F276E will probably not
be able to address an external memory at 64MHz with 0 wait states (under evaluation).
● XPERCON register bit mapping modified according to new peripherals implementation
(not fully compatible with ST10F269).
● Bondout chip for emulation (ST10R201) cannot achieve more than 50MHz at room
temperature (so no real-time emulation 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 500mV of hysteresis) and standard CMOS (with up to 800mV of hysteresis).
● Output transition is not programmable.
● CAN module is enhanced: ST10F276E implements two C-CAN modules, so the
programming model is slightly different. Besides, the possibility to map in parallel the
two CAN modules is added (on P4.5/P4.6).
● On-chip main oscillator input frequency range has been reshaped, reducing it from 1-
25MHz down to 4-12MHz. This is a high performance oscillator amplifier, providing a
very high negative resistance and wide oscillation amplitude: when this on-chip
amplifier is used as reference for Real-Time Clock 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 of 4-8MHz:
this will allow a power consumption reduction when Real-Time Clock is running in
Power Down mode using as reference the on-chip main oscillator clock.
● A second on-chip oscillator amplifier circuit (32kHz) is implemented for low power
modes: it can be used to provide the reference to the Real-Time Clock counter (either
in Power Down or Stand-by mode). Pin XTAL3 and XTAL4 replace a couple of VDD/VSS
pins of ST10F269.
● Possibility to re-program internal XBUS chip select window characteristics (XRAM2 and
XFLASH address window) is added.
