Product Attributes

Features

• Compatibility: Fully compatible with VPC3 operating in DPV0 mode at 3.3V supply voltage; fully compatible with SPC3 operating in DPV0 mode except for the difference in supply voltage
• Processor Interface: Supports both Intel and Motorola processor interface modes; interface mode configurable via XINT/MOT and MODE pins; direct access to internal dual-port RAM through synchronous/asynchronous 8-bit data interface and 11-bit address bus
• Clock: Requires 48MHz external clock input; capable of outputting 24MHz/12MHz clock to external processor
• Software Interface: Integrates 1.5k dual-port RAM primarily for interfacing between APC3 and software; dual-port RAM divided into 192 segments, each containing 8 bytes; software accesses dual-port RAM on a segment basis
• Status Indication: MAC status within APC3 can be queried at any time via status registers, including Offline/Passive-idle, DP-State, WD-State, baud rate status, etc.; interrupt request registers provide notification of various external events to retrieve associated data such as user extended parameter data
• Baud Rate Detection: APC3 supports automatic baud rate detection in the range of 9.6Kbps~12Mbps; supported baud rates: 12M, 6M, 3M, 1.5M, 500k, 187.5k, 93.75k, 45.45k, 19.2k, 9.6k (bps)
• Temperature Characteristics: Storage temperature: -65~150℃; Operating temperature: -40~85℃; Junction temperature: -40~85℃

Applications

• I/O modules for PLC and DCS
• DP network connectivity
