MCU Family Gains Member With An On-Chip ADC

Part of the 51LPC family of 80C51-based microcontrollers, the 87LPC767 device features an on-chip four-channel multiplexed eight-bit a/d converter. Like the other members of this microcontroller family, the device provides a brownout detection function, a wide operating-voltage range, power-on reset, and a watchdog timer. The device also includes an on-chip oscillator that provides five user-programmable modes for tuning the performance and power consumption of the device. Using the oscillator frees two additional pins for I/O use, increasing the total I/O pin count from 16 to 18. Available in 20-pin PDIPs and SOIC packages, the device is priced at $1.63 each/10,000.
