Product details
Overview
DVA16XP187 from Microchip Technology Inc. is a device adapter for the MPLAB ICE 2000 in-circuit emulator system, designed specifically for 18-pin DIP-packaged PIC16F716 microcontrollers. It provides target interface connectivity, includes dual oscillator circuitry supporting TIMER1 oscillator input (32–40 kHz), and features four mechanical switches for configurable pin routing including RB1, RB2, RB3, CCP1, T1CKI, and oscillator modes. It enables accurate emulation of oscillator behavior and peripheral timing during firmware development.
For engineers reviewing the DVA16XP187 datasheet, DVA16XP187 pinout, DVA16XP187 application, or DVA16XP187 equivalent, this adapter is critical for validating PIC16F716-based designs under real-world clocking, I/O contention, and low-voltage operation conditions - especially where TIMER1 oscillator fidelity, MCLR routing, and external clock source integration are required.
Technical Context
The DVA16XP187 interfaces between the PCM16YJ0 processor module and PIC16F716 target hardware via an 18-pin DIP footprint (0.300" width). Its on-board second oscillator supports precise 32–40 kHz TIMER1 oscillation independent of main system clock, with switch-controlled routing of RB1 to T1CKI and RB3 to either general-purpose I/O or CCP1 function.
Switch configuration determines signal path allocation: S2-1/S2-2/S2-3 define RB1/RB2/RB3 roles, while S1 and S2-1 jointly configure TIMER1 Clock Input or TIMER1 Oscillator Input modes. No jumper configuration is required - all functionality is managed exclusively through mechanical switch positions per Table 5-6.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Target Device | PIC16F716 18-pin DIP - exact pin-compatible interface for emulation and debug |
| Footprint Type | 0.300" wide DIP socket - matches standard 18-pin DIP layout (A = 2.000", B = 2.100") |
| Timer1 Oscillator Range | 32–40 kHz - enables accurate low-frequency peripheral timing validation without external crystal |
| Switch Count | Four mechanical switches (S1, S2-1, S2-2, S2-3) - fully manual, no firmware or configuration software needed |
| Signal Routing Options | RB1→T1CKI, RB2→emulator/oscillator, RB3→GPIO or CCP1, OSC1/OSC2 selection - preserves full functional coverage of PIC16F716 I/O mapping |
| Power Interface | No active power regulation - draws ≤10 mA from target VCC for oscillator circuitry only when emulator is powered externally |
Pinout & Package
Package: 18-pin DIP (0.300" width), dimensions A = 2.000", B = 2.100" per Table 6-1. Mounts directly to target board or via transition socket; no soldering required for evaluation use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (MCLR) | Master Clear Input | Routed to emulator or held high via internal pull-up depending on S2-3 position; critical for reset synchronization during debug |
| Pin 6 (RB1) | Port B Bit 1 | Configurable as T1CKI (TIMER1 clock input) or general I/O via S2-1 switch - enables direct peripheral timing injection |
| Pin 7 (RB2) | Port B Bit 2 | Routed to emulator silicon or oscillator device via S2-2 - supports oscillator feedback loop testing |
| Pin 8 (RB3) | Port B Bit 3 | Switch-selectable as GPIO or CCP1 (Capture/Compare/PWM) via S2-3 - preserves PWM debugging capability |
| Pin 13 (OSC1) | Oscillator Input | Connected to target crystal or RC network; load capacitance 5–10 pF - matches PIC16F716 data sheet oscillator drive requirements |
| Pin 14 (OSC2) | Oscillator Output | Drives external crystal; same 5–10 pF load - ensures accurate frequency reproduction during emulation |
Key Features
| Feature | Design Value |
|---|---|
| Dual Oscillator Architecture | Primary oscillator (OSC1/OSC2) + dedicated 32–40 kHz TIMER1 oscillator - enables concurrent main clock and peripheral timing validation |
| Manual Switch Configuration | Four-position mechanical switch bank (S1, S2-1–S2-3) - eliminates need for firmware setup or jumper shunting; deterministic, repeatable routing |
| PIC16F716-Specific Pin Mapping | Exact 1:1 DIP pinout alignment with RB1, RB2, RB3, CCP1, MCLR, OSC1, OSC2 - guarantees signal integrity and eliminates adapter-induced skew |
| Low Target Loading | ≤10 mA max current draw from target VCC - avoids interference with low-power or battery-operated PIC16F716 applications during debug |
| No Active Components | Passive routing + discrete oscillator ICs only - no voltage translation, level shifting, or digital logic that could mask timing faults |
Applications

FAQ
What is the primary target microcontroller supported by the DVA16XP187?
The DVA16XP187 is explicitly designed for the PIC16F716 18-pin DIP microcontroller. Its pinout, switch configuration table (Table 5-6), and mechanical footprint (A = 2.000", B = 2.100") are all specified in DS51140M for this exact device. It does not support other 18-pin PIC variants unless explicitly listed in the MPLAB ICE 2000 Readme file.
Does the DVA16XP187 require any firmware or software configuration to operate?
No. The DVA16XP187 uses only mechanical switches (S1, S2-1, S2-2, S2-3) for signal routing - no firmware, drivers, or MPLAB IDE settings are needed to configure its basic functionality. All routing decisions (e.g., RB3 → CCP1 vs. GPIO) are made physically via switch position per Table 5-6 in DS51140M.
How does the DVA16XP187 handle oscillator loading for crystal-based designs?
The DVA16XP187 presents a 5–10 pF capacitive load on OSC1 and OSC2 pins, matching the PIC16F716 data sheet specifications. This ensures accurate crystal oscillation frequency and startup behavior during emulation - critical for validating timing-sensitive applications like UART communication or PWM generation.
Can the DVA16XP187 be used with surface-mount PIC16F716 packages such as SOIC or TQFP?
No - the DVA16XP187 is a dedicated 18-pin DIP adapter. To emulate surface-mount PIC16F716 variants, a compatible transition socket (e.g., Samtec DWM series) must be used between the DVA16XP187 and the target board. Direct SOIC/TQFP connection is not supported per DS51140M Section 6.2.
What is the maximum current drawn by the DVA16XP187 from the target system?
The DVA16XP187 draws up to 10 mA from the target VCC supply, solely to power its on-board oscillator circuitry. This value is consistent across all operating voltages (2.0–5.5 V) and is documented in Section 5.0 of DS51140M - it does not scale with emulator activity or target clock frequency.
