Applied Materials HAMAT Series Technical Notes

The Evolution of HAMAT Architecture

Applied Materials introduced the HAMAT serial server family as a transitional solution during the industry-wide migration from RS-232-native VME and PCI backplane architectures to USB-centric host computing platforms in the early 2000s. Early HAMAT units were single-port RS-232 converters operating at fixed baud rates up to 115,200 bps. Subsequent revisions introduced multi-port configurations, hardware flow control (RTS/CTS), and isolated ground planes to suppress EMI generated by RF-intensive etch and CVD chambers.

The U2M-84 variant (part number 0190-22545, assembly 1D10-102451-12, GSL reference 604) represents a mature mid-generation design with an 8-port RS-232 output bus on a single USB upstream connection. This architecture eliminated the need for multiple USB host ports and reduced cable management complexity inside equipment enclosures. As Applied Materials transitioned newer platforms to Ethernet-based serial device servers (e.g., Lantronix UDS series integrated under AMAT part numbers), the HAMAT USB family entered a maintenance-only lifecycle. No direct pin-compatible successor exists; replacement requires either sourcing original HAMAT units or engineering a validated substitute with equivalent driver support under the AMAT software stack.

Quality Control for the HAMAT Range

HAMAT USB-to-RS-232 serial servers present specific failure modes that require targeted test procedures beyond standard power-on verification. DriveKNMS applies the following protocol to all HAMAT units prior to shipment:

USB Enumeration Test: Each unit is connected to a calibrated USB 2.0 host and verified to enumerate all declared COM ports correctly under both Windows and Linux driver stacks (FTDI and Prolific chipset drivers as applicable).
Per-Port RS-232 Loopback: All 8 RS-232 ports on U2M-84 units are individually tested with a loopback connector at baud rates of 9600, 19200, 38400, 57600, and 115200 bps. Bit error rate must be 0 across a 10,000-character test string per port.
Flow Control Verification: RTS/CTS hardware handshaking is validated on each port using a serial protocol analyzer. DTR/DSR signaling is verified independently.
EMI Susceptibility Check: Units are powered and operated adjacent to a 13.56 MHz RF source (simulating etch chamber proximity) for 30 minutes. No COM port dropout or data corruption is acceptable.
Thermal Cycling: Units are cycled from 0°C to 55°C across three cycles and re-tested for full functionality at temperature extremes.
Visual and Mechanical Inspection: Enclosure integrity, USB connector retention force, DB9 port thread condition, and PCB visible layer inspection are completed under 10x magnification.
