DLP-245PB-G

Overview

The DLP-245PB-G is a USB to microcontroller module integrating an FTDI FT245RL FIFO chip and a Microchip PIC16F877A processor. It enables rapid development by providing a preprogrammed interface for accessing port pins, A/D conversion, EEPROM, and external sensors via USB. The module supports data transfer rates up to 2 megabits per second and operates in bulk or isochronous modes. It includes royalty-free VCP and D2XX drivers for Windows, Mac OS, and Linux, allowing the peripheral to function as a standard COM port or be accessed directly via DLL software interfaces without requiring deep USB protocol knowledge.

Feature Summary

• Integrates Microchip PIC16F877A with 8K FLASH ROM, 368 bytes RAM, and 10-bit A/D converter
• Provides 18 digital I/O lines (6 configurable as A/D inputs) plus an 8-bit data bus
• Supports USB 1.1/2.0 compatibility with transfer speeds up to 2 Mbps
• Includes preprogrammed 'Token I/O' firmware for basic port control and sensor access

Applications

• Prototype development
• USB ISDN and ADSL modems
• USB interface for digital cameras
• High-speed USB instrumentation
• USB smart-card readers

Procurement Notes

Verify that the specific unit received matches the DLP-245PB-G designation. Confirm the presence of the FT245RL and PIC16F877A components on the board. Ensure the required MPROG utility and D2XX drivers are downloaded from official sources if custom VID/PID programming is needed. Check for lead-free compliance markings consistent with the '-G' suffix.

Selection Notes

Select this module when a ready-to-use USB-to-parallel interface with embedded processing is required. It is suitable for applications needing immediate access to GPIO, A/D, and EEPROM functions without writing low-level USB drivers. Consider the 8K FLASH limit for complex user code and the availability of a 5-pin programming header for reprogramming the microcontroller.

Part Context

This module is part of DLP Design's line of USB development tools, combining FTDI's serial-to-FIFO technology with Microchip's PIC architecture. It serves as a bridge between host computers and electronic peripherals, simplifying the integration of USB connectivity into custom hardware designs by handling the USB protocol automatically.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users requiring similar functionality may need to evaluate other modules from DLP Design or design a custom solution using the FT245RL and PIC16F877A components separately.
