Mandeno Granville is dedicated to providing 'best in class' tools, and design services.
The total C51 device market is ~$1.3Billion, making it the easily
the leading 8 bit uC.
The C51 is also the most process-modern, small uC, now shipping in 0.25u FLASH.
The C51 controllers, provide the most powerful core in 20 pin packages, and with a range from 20 to 208 pins, and up to 100MIPS, offers the widest horsepower range of ANY microcontroller family.
With HW Mul/Div, True Boolean Processor, HW UART, INT Priority, multisourcing with over TWENTY FLASH chip suppliers, the C51 is squeezing the simpler cored, paged and single sourced, alternatives towards the 4 bit controller segment.
Volume prices for Small FLASH C51 cored controllers are well under $US1!
With a core OPTIMISED for Embedded Control, and Speeds to 100 MIPS (!), the C51 outperforms the simpler RISC controllers (AVR, ST6, PIC etc) in both CODE size, and Speed !
