Philips Introduces 80C51X2 Microcontroller Family
Royal Philips Electronics (San Jose, CA) announced its new 80C51X2 family of eight-bit microcontrollers for hand-held portable devices. The new 80C51X2 family support both 6-clock and 12-clock operation, and perform over a wide operating range of 2.7V to 5.5V with up to 50-percent less power consumption when compared to the original 12-clock 80C51 family.
Key features of the 80C51X2 family include a high-performance, static, CMOS 80C51 design for low-power, low-voltage systems; two software selectable modes of power reduction, (idle or power-down) for ultra-low power operation; an idle mode that freezes the CPU while allowing the RAM, timers, serial port, and interrupt system to continue functioning; and a power-down mode that saves the RAM contents, but freezes the oscillator, causing all other chip functions (except response to external interrupts/reset) to be inoperative.
The complete 80C51X2 family of microcontrollers is immediately available in 44-pin PLCC, LQFP and PDIP packages. The 87C51X2, 87C52X2, 87C54X2 and 87C58X2 OTP devices start at $1.05 in quantities of 20,000 units. The 89C51X2, 89C52X2, 89C54X2 and 89C58X2 Flash memory devices start at $1.25 for 20,000 units. The 80C31X2 and 80C32X2 ROMless devices start at $0.90 in 20,000 units. The 80C51X2, 80C52X2, 80C54X2 and 80C58X2 ROM devices start at $1.00 in quantities of 25,000 units.
