Sunnyvale, Calif. Philips Semiconductors has added the 87LP-C769 and the 8xC554 to its family of 8-bit microcontrollers (MCUs).
Product marketing manager Kevin Gardner said the MCUs employ a six-clock core design that offers significant power consumption, noise immunity and electrostatic discharge advantages over the 12-clock 80C51 architecture.
The MCUs can be configured for industrial control applications such as speed, temperature and power controls. The 87LPC769, manufactured on a 0.50-micron process, features an 8-bit digital-to-analog converter and a dedicated four-channel, 8-bit analog-to-digital converter that is software-configurable as a second D/A. The A/D can be used in applications ranging from volume control in an MP3 player to speed controls in dc motors. It also includes 4 kbytes of one-time programmable (OTP) memory and 128 bytes of RAM.
The 8xC554, manufactured on a 0.65-micron process, features an eight-channel, 10-bit A/D plus 16 kbytes of OTP memory, 512 bytes of RAM, UART communications modes and integrated power management support. It's aimed at applications such as battery power management and precision measurement and control.
The 87LPC769, a member of Philips' 51LPC family, is available in a 20-pin thin shrink small-outline package that measures 4.4 x 6.5 x 1.1 mm. It's specified over the extended industrial temperature range of -40 degrees C to +125 degrees C, incorporates UART and I2C serial communications and is priced at $2.68 in quantities of 10,000. The 87C554, in a 64-pin low-profile quad flat pack, is priced at $4.45.
