DPB2 is a unique development system for the entire Dallas Secure Microcontrollers. These are 8051 cores plus nonvolatile memory, clock and calendar, watchdog timer, and 10-year lithium battery, all in one module. All you need to add is a crystal, power and any special I/O.

DPB2 is the fastest way to develop a system with Dallas Secure Micros. The Systronix DPB2 development system adds a linear regulator, LCD and keypad interfaces, 8-bit ADC, 4 bits of digital input, 4 bits of high current open-drain output, and a large prototype area with colander ground plane. DPB2 accepts DIP40, SIMM40 and SIMM72 modules.

Convert DPB2 to a heavy use DS5000 DIP40 programmer with this adapter.
