Keil C51 Supports Philips MX Devices

Keil Software is pleased to announce support for the Philips Semiconductors MX Devices. The new Philips MX Architecture expands the address space of the 8051 to 16 megabytes. New compiler, assembler, and linker technology from Keil Software eases migration of your existing 8051 applications to this enhanced architecture.

New instructions in the MX make memory access faster than possible with standard 8051 devices.
