ARM7TDMI for automotive, flash memory up to 1Mbyte, on-chip Vcore regulator, CAN-BUS, UART, ADC, DAC, ...

3.4 NXP/Philips LPC2000

• Product homepage: http://www.standardics.nxp.com/products/lpc2000/
• Technical resources: http://www.arm-development.com/lpc2000

Righ peripherial set, many of these chips require two power supply voltages (1.8V for Core and 3.3V for I/O).

3.5 ST STR710

• Product homepage: http://mcu.st.com/mcu/inchtml-pages-str7.html
• Technical resources: http://www.arm-development.com/str7

General purpose microcontrollers, quite rich peripherial set, they require two power supply voltages (1.8V for Core and 3.3V for I/O), resetting circuitry and oscillator (not just a crystal).

3.6 Texas Instruments TMS470

• Product homepage: http://www.ti.com/tms470
