DP Communication Chip
APC3 is a fieldbus dedicated chip for the development of PROFIBUS DP intelligent slaves, supporting the complete DPV0 protocol. APC3 is fully compatible with SPC3LV and VPC3 working in DPV0/3.3V/1.5K dual-port RAM mode. It can be replaced directly without modifying the software/hardware design. Products developed with APC3 can pass the consistency and interoperability tests of DP products organized by PI. APC3 has faster message response time and lower power consumption.

DP Communication Controller APC3 is an ASICs chip for PROFIBUS DP intelligent slave station development. APC3 supports the DPV0 part of the PROFIBUS DP standard.
1. Pin definition is compatible with VPC3 in 2K mode
2. Automatic identification of 9.6Kbps~12Mbps baud rate
3. Support Intel and Motorola processor interface modes
4. Integrated 1.5KByte dual-port RAM
5. Working temperature: -40℃~85℃
6. Power supply voltage: 3.3V
7. Compatible with SPC3LV
