New Microcontroller Selection after 8051

[pramodjaipur]

Hi,

We are working on 8051 project; The code size after compile is around 100K +

We are using External Uart, RTC, Latch & Logic's  EP-ROM, SRam. Watchdog IC. etc.

8051 supporting well, but due to code banking and more memory requirements, i want to shift with other controller, needed same functions.

I checked with ARM7, but need to modify in the Hardware too.

Please help me to selecting new chip.

thanks for your suggestions.

The family's 40MHz 8032 core supports USB and many other on-chip peripherals making these devices a complete solution for a broad variety of embedded control applications. With up to 288-Kbyte of Flash memory and 8-Kbyte of SRAM, ST offers the largest memory densities for an 8051-class MCU available today. A $149 development kit coupled with third-party development tools is everything required to implement and validate a design.

Also take a look at www.maxim-ic.com
they have 8051 cores too


                        good luck with 8051

Thanks for your reply,  If new design is required to use this device, better we can go with other "uC"

As we written the code in C and using compiler, better we can use some what latest.

Please suggest.

why not using an atmel avr?
you can use ATmega2560 containing 256KB code 8Kb ram 4 usart 5 timers 16 10bit adc and a lot of other stuff.

Why not using a C8051F120 with 100 MIPS, 128 kB Flash, 8448 bytes data RAM, 8input AMUX 12-Bit ADC, Programmable amplifier gain: 16, 8, 4, 2, 1, 0.5, Two 12-Bit DACs, Five 16-bit timers, 100-Pin, 64 port I/O;, On-Chip JTAG Debug, and etc. Please see SILICON LABS site www.silabs.com for more info.
