Product Overview: HART Modem Chips
Microcyber provides direct-replacement HART modem chips that cut BOM costs by more than 50%, without redesigning your existing hardware.
The HT5700 and HT1200M are pin-compatible alternatives to the AD5700 and A5191HRT. They are HART-certified, mass-production ready, and backed by local technical support.
The Problem We Solve
For many instrument OEMs, the AD5700 and A5191HRT have long been the only viable options, leading to single-vendor pricing dependencies. Microcyber’s HT5700 and HT1200M offer procurement and engineering teams a certified alternative that can be seamlessly integrated into existing designs—no schematic changes, no firmware rewrites.
Three Reasons for Procurement Teams to Switch
- Substantial Cost Reduction:
Replacing the AD5700 with the HT5700 cuts HART modem BOM costs by over 50%, with even greater savings in high-volume production of pressure transmitters, flow meters, and temperature instruments.
- Seamless Integration:
Pin-level compatibility lets you keep existing PCB layouts, schematics, and firmware intact—just swap the chip and stay on schedule.
- Mass Production Ready:
Both chips are in mass production with stable lead times, providing reliable supply chain security beyond just sample availability.
