Cortex with LCD or 8051

leo ren

Hi all kindly help me.
I'm looking for possible MCU to use, basic requirements would be:
1. on-chip RTC or mcu that can generate accurate time for RTC
2. LCD of around 100 segments, on-chip driver, or software driver
3.SPI,I2C and UART on-chip
4. ARound 32k flash, 1-2k RAM
5. GPIO of aorun 30pins for LCD if software, 1set of SPI,1set of I2C, UART, and 5 extra pins
6. LOW COST

Possible cortex m0,m3 or 8051 family.
Help really appreciated

Thank you

    Thank you for brief explanation. to lower my requirements, I just need Micro that has RTC,LCD(100segments=4*25=29GPIO),sleep mode and low cost.base on my search i think no cortex that has it. if you've click that holtek site, that would be my perfect choice, but some consideration needed, as like reliable tools and more...

    thank you
