High-Performance 8051 MCU + 8KB FRAM

The VRS51L3174 is a high performance, 8051-based Microcontroller 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 the VRS51L3174s memory sub-system features 64KB of Flash and 4352 bytes of SRAM and 8192 Bytes of nonvolatile FRAM (ferroelectric random access memory) 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 I2C 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 VRS51L3174 operates from 3.0 to 3.6 volts over the industrial temperature range and is available in a QFP-44 package. The device features an active-low reset and is pin-compatible with an industry standard 8051 Microcontroller footprint. By Ramtron Corporation
