查看全系列相关产品产品概述
The DS5000FP-16+ is a soft microprocessor chip in 80 pin QFP package. This 8051 compatible processor is based on NV RAM technology. It is substantially more flexible than a standard 8051 and provides full compatibility with 8051 instruction set, timers, serial port and parallel I/O ports. The user can program and then reprogram microcontroller while in-system by using NV RAM instead of ROM. The application software can even change its own operation which allows frequent software upgrades, adaptive programs and customized systems. In addition, by using NV SRAM, the DS5000FP is ideal for data logging applications and it connects easily to Dallas real time clock for time stamp and date. It uses a nonmultiplexed byte wide address and data bus for memory access. This bus can perform all memory access and provides decoded chip enables for SRAM. Data is maintained for over 10 years with a very small lithium cell.
- Supply voltage range from 4.75V to 5.25V
- Maximum clock speed of 16MHz, accesses between 8KB and 64KB of non-volatile SRAM
- Operating temperature range from 0°C to +70°C
- In-system programming via on-chip serial port and can modify its own program or data memory
- Early warning power fail interrupt, watchdog timer and user supplied lithium battery backs
- Executes encrypted programs to prevent observation, security lock prevents download
- 128bytes scratchpad RAM, two timer/counters, on-chip serial port and 32 parallel I/O port pins
- 1MHz to 16MHz oscillator frequency & 12.5V to 13V programming supply voltage (parallel program mode)
- User SRAM for program/data storage and supports UART interface and crash proof operation
- Operating current of 36mA at 16MHz and idle mode current of 6.2mA at 12MHz
