VRS51L2070
High-Performance 8051 MCU
Overview
The VRS51L2070 constitute a family of high performance, 8051based microcontrollers coupled with a fully integrated array of peripherals for addressing a broad range of embedded design applications.

Based on a powerful 40-MIPS, single-cycle, 8051 microprocessor, these MCU's memory sub-system features 64KB of Flash and 4352 bytes of SRAM memory. Support peripherals include a hardware based arithmetic unit capable of performing complex mathematical operations, a JTAG interface for Flash programming and non-intrusive in-circuit debugging/emulation, an internal oscillator, and a watchdog timer. Communication and control of external devices is facilitated via an assortment of digital peripherals such as an enhanced, fully configurable SPI bus, an IІC interface, dual UARTs with dedicated baud rate generators, three 16-bit timers, 8 PWM controllers each with a 16-bit timer, and 2 pulse width counter modules. The VRS51L2070 device op
