Product details
Overview
DVA16XP182 from Microchip Technology is a device adapter for the MPLAB ICE 2000 in-circuit emulator system, designed specifically for PIC16C712 and PIC16C716 18-pin DIP microcontrollers. It provides target interface connectivity, includes a dedicated second oscillator for TIMER1 (32–40 kHz), and features four mechanical switches for configurable pin routing including RB1, RB2, RB3, CCP1, T1CKI, and oscillator inputs.
For engineers reviewing the DVA16XP182 datasheet, DVA16XP182 pinout, DVA16XP182 application, or DVA16XP182 equivalent, this adapter enables precise emulation of legacy PIC16C7xx devices with hardware-matched oscillator behavior, switch-controlled peripheral signal routing, and direct DIP footprint compatibility-critical for legacy firmware development, debug validation, and production test fixture integration.
Technical Context
The DVA16XP182 interfaces between the PCM16XE1 processor module and PIC16C712/716 target devices using an 18-pin DIP footprint. Its dual-oscillator architecture supports both internal emulation clocking and external target-sourced timing, with dedicated circuitry to replicate TIMER1 oscillator operation at 32–40 kHz independent of the main system clock.
Four mechanical switches (S1, S2-1, S2-2, S2-3) enable runtime reconfiguration of RB1, RB2, RB3, CCP1, T1CKI, and oscillator input paths-allowing selection between emulator silicon routing and on-board oscillator device routing without soldering or hardware modification.

FAQ
What microcontrollers does the DVA16XP182 support?
The DVA16XP182 is explicitly designed for PIC16C712 and PIC16C716 18-pin DIP microcontrollers. It is not compatible with PIC16F716 or other derivatives-the switch logic, oscillator circuitry, and pin mapping are validated only for these two parts per DS51140M Section 5.5. Using DVA16XP182 with unsupported devices may result in incorrect signal routing or missing oscillator functionality.
How does the DVA16XP182 handle TIMER1 oscillator emulation?
The DVA16XP182 integrates a dedicated second oscillator circuit that generates a stable 32–40 kHz clock for TIMER1 emulation. This hardware oscillator replicates the asynchronous behavior of the PIC16C712/716's internal TIMER1 oscillator, independent of the main system clock. Switch settings S2-1, S2-2, and S1 configure whether this signal feeds T1CKI or drives the oscillator pins directly-enabling accurate timing validation without software adjustment.
What are the mechanical switch functions on the DVA16XP182?
The DVA16XP182 uses four mechanical switches: S1, S2-1, S2-2, and S2-3. S2-1 controls RB1 routing (to T1CKI or emulator silicon); S2-2 controls RB2 routing; S2-3 selects RB3 function (general I/O or CCP1); and S1, in combination with S2-1/S2-2, configures TIMER1 clock source (external or internal oscillator). These switches replace soldered jumpers-allowing rapid reconfiguration during debug sessions without hardware changes.
Is the DVA16XP182 compatible with modern MPLAB development tools?
The DVA16XP182 is designed exclusively for use with the legacy MPLAB ICE 2000 emulator system and PCM16XE1 processor module. It is not compatible with MPLAB ICD, PICkit, or REAL ICE programmers/debuggers. The adapter requires MPLAB IDE v7.x or earlier and depends on the discontinued ICE 2000 hardware platform-no driver or firmware updates exist for modern IDE versions.
Does the DVA16XP182 require external power from the target board?
Yes-the DVA16XP182 draws up to 10 mA from the target board's VCC rail even when the MPLAB ICE 2000 emulator pod supplies power to the processor module. This current powers the on-board oscillator circuitry and switch logic. Target boards must maintain stable 5V ±10% during emulation; voltage droop below 4.5V may cause oscillator instability or communication errors with the DVA16XP182.
