NEC Electronics Debuts V850ES/PM1 Microcontroller
NEC Electronics Corp. (Santa Clara, CA) announced the latest addition to its popular V850ES™ family of 32-bit, RISC microcontrollers, the V850ES/PM1™, which is suitable for electronic measuring instruments such as power meters.
The V850ES/PM1 controller uses a six-channel (12-input), analog-to-digital (A/D)converter; and a fast and high-resolution delta-sigma A/D converter that offers stability and reading of analog signals with 16-bit resolution. The functionality is possible due to an on-chip reference voltage generator and reference voltage-output pin that enables the controller and converter to operate in a single-chip configuration, which lowers the component count and also lowers overall system cost.
The V850ES core that drives the V850ES/PM1 device delivers a compelling power/performance ratio of 2.8mW per million instructions per second. Several low-power standby modes maximize battery life, while a low signal-to-noise ratio of 76dB ensures accurate measurements in target applications.
Samples of the V850ES/PM1 microcontroller with 128KB of mask read-only memory and 10KB of random access memory in a 100-pin, plastic, low-profile, quad-flat package (LQFP) are scheduled for availability in February 2003, priced in the US at $10 each in 10,000-unit volumes. Volume production is scheduled to begin in the second quarter of 2003.
