New LPC90x/LPC91x devices offer lower system cost and increased functionality
22 Sept, 2003 - Royal Philips Electronics announced two new families of 8-bit microcontrollers (MCUs) designed for cost-conscious, high volume embedded applications. The LPC90x family of 8-pin MCUs and the LPC91x family of 14-pin MCUs deliver the latest innovations in microcontroller technology to designers of consumer, automotive, and industrial control products, ranging from battery powered devices to white goods. With byte-erasable flash memory, enhanced timing functions and on-chip serial communications, designers using the LPC90x and LPC91x can benefit from lower total system cost and miniature footprint while enjoying additional functionality.Philips' LPC90x and LPC91x MCU families include nine devices that integrate important features in compact 8- or 14-pin packaging. Both families feature 1K byte-erasable Flash memory organized into 256-byte sectors and 16-byte pages. The advantage of having byte-erasable Flash memory is that any byte(s) can be used as non-volatile data storage thus enhancing the flexibility and performance of the MCU. Power-down current is specified at 1uA typical (5uA worst case) making the part very well suited for battery operated applications.
The LPC90x and LPC91x devices feature up to four 16-bit counter/timers with the option to generate a Pulse Width Modulation (PWM) signal output. The timers can also be used as a system timer or act as a real-time clock. The new family also includes the industry's first 8-pin MCU to integrate a UART on-chip, enabling communication between system components.
Tools and SupportPhilips offers low-cost, easy to use development tools to support customer development with the LPC90x/LPC91x devices.
Price and AvailabilityPhilips' LPC90x and LPC91x families of microcontrollers are available now.
