Product Overview
VPC3+C is a PROFIBUS DP slave ASIC by Profichip (Yaskawa), pin and software compatible with Siemens SPC3 for direct PCB replacement. It fully hardware-implements DP-V0 cyclic data, DP-V1 acyclic parameter access and DP-V2 synchronous communication protocols. The integrated 4KB dual-port SRAM acts as low-latency data buffer between RS-485 transceivers and host MCUs. All frame encoding, decoding and error correction run on-chip up to 12Mbps, cutting real-time computation load of external microcontrollers. Packaged in compact 44-PQFP (10×10mm), it serves factory automation, servo drives and distributed IO equipment.
Core Advantages
Full Hardware PROFIBUS Protocol Processor
Independent hardware engine handles DP-V0 / DP-V1 / DP-V2 protocol stack, eliminating host MCU timing errors and extra firmware development workload.
4KB Shared Dual-Port Communication RAM
Dual-port SRAM allows simultaneous data access by host CPU and PROFIBUS communication core, no internal bus conflict during data transmission.
Configurable 8-bit Parallel MCU Interface
Supports multiplexed / non-multiplexed bus timing (Intel / Motorola mode), compatible with most mainstream 8-bit embedded microcontrollers.
Max 12Mbps PROFIBUS Baud Rate
Reaches the top transmission speed of PROFIBUS DP with auto baud rate detection, low signal jitter for high-precision automation control loops.

Frequently Asked Questions
Q1: Are VPC3+C parts 100% original new stock?
A: All VPC3+C are brand-new original chips from Profichip Yaskawa. Every batch passes strict incoming QC with complete lot traceability, shipped in factory ESD trays to prevent pin oxidation and damage.
Q2: What are the upgrades of VPC3+C compared to legacy VPC3?
A: VPC3+C is fully pin-compatible upgrade. It adds hardware DP-V1 parameter access and DP-V2 synchronous communication, with optimized low-power 3.3V core design.
Q3: Is an external crystal oscillator required for VPC3+C?
A: Yes, a dedicated 48MHz external crystal is mandatory. It ensures stable timing under 12Mbps high-speed PROFIBUS communication for internal baud rate generation.
Q4: How can I get driver codes, datasheets and bulk prices?
A: Fill in your project details and required quantity on the inquiry form. Our technical team will send official registers, driver templates and tiered bulk prices within 24 working hours.
Q5: Can I apply for free engineering samples of VPC3+C?
A: Yes, we support free small-batch engineering samples for project verification. Leave your project information and sample demand via the inquiry form to apply.
Q6: What is the lead time for mass order delivery?
A: In-stock items ship within 1-2 working days. For large bulk orders out of stock, the standard production lead time is 2-4 weeks.
Q7: What is the warranty period for VPC3+C chips?
A: All original chips carry a 1-year factory quality warranty. We support replacement for defective parts caused by original manufacturing flaws.
Q8: Can VPC3+C directly replace Siemens SPC3 without PCB modification?
A: Absolutely. VPC3+C maintains fully consistent pinout, hardware and software logic with Siemens SPC3, no PCB redesign or program adjustment needed.
