DLP-245PB-G
USB / Microcontroller Module (Lead-Free)
The DLP-245PB-G combines the same USB interface used in the DLP-USB245M-G module
with a Microchip PIC microcontroller to form a rapid development tool. The 16F877A
microcontroller is preprogrammed with basic functionality for accessing the port pins and
can be reprogrammed with user hex code via a 5-pin header using a device programmer
(purchased separately).
DLP-245PB-G FEATURES
• Send/receive data over USB to a host computer at up to 2 megabits per second
• 18 digital I/O lines (6 can be configured as A/D inputs) plus the 8-bit data bus available for
interfacing to user electronics
• Microchip 16F877A processor with 8K FLASH ROM, 368 bytes RAM, and a multi-channel,
10-bit A/D converter
• “Token I/O” code preprogrammed into the 16F877A’s ROM for basic port pin input/output
capability including access to the A/D, EEPROM, and external digital temperature sensors.
ROM can be easily erased and reprogrammed with a user-supplied compatible programmer
• No in-depth knowledge of USB is required as all USB protocol is handled automatically by the
on-board FT245RL and its support circuitry
