NEC Adds V850ES/PM1 to V850ES MCU Family

February 11, 2003 by Jeff Shepard

NEC Corp. (Japan) announced that it has expanded its V850ES 32-bit microcontroller (MCU) family with the addition of the V850ES/PM1 device targeted for use in electronic measuring instruments such as power meters. The V850E/PM1 uses a six-channel (12-input), 16-bit, delta-sigma analog-to-digital converter to offer improved stability and precise reading, and features an on-chip, reference voltage generator and reference voltage-output pin that enables the controller and converter to operate in a single-chip configuration.

The V850ES core within the MCU consumes a maximum of 2.8mW/MIPS and features several low-power, standby modes to maximize battery life. It also exhibits an SNR of 76dB to ensure accuracy in target applications. In addition, the V850ES/PM1 MCU uses a separate bus configuration supporting access speeds up to 10MHz on an external bus, which enables high-speed data access and easy connection to external SRAM and Flash memory in systems that require a large number of parameters or data tables.

Samples of the V850ES/PM1 MCU with 128KB of mask ROM and 10KB of RAM in a 100-pin LQFP are now available at $10 each in 10,000-unit volumes.
