Today we’ll be taking a look at an old device the Netgear ProSafe Wireless Firewall/Print Server (FM114P), it’s a 11Mbps 802.11b parallel print server / access point with 4x 10/100 network ports and 1x 10/100 WAN port.
One screw later and we’re in.
We’ve quite a bit of logic chips under the wireless card and a small heatsink for the processor and an 802.11b Wireless PCMCIA card (XI-325) connected via some right angle pin headers – they may not have had enough room to fit it in or it was easier to buy it off the shelf than design it themselves. For power side of things, we have a LM2576 SMPS and 2x 1084CM linear regulators. PCB date of 35th week, 2002.
The logic chips comprise of –
2x 74HC174 (Hex D-type flip-flop with reset)
74LVC74A (Dual D-type flip-flop with set and reset)
74F125 (Quad buffer)
74LVC14A (Hex inverting schmitt trigger)
2X 74LVC32A (Quad 2-input OR gate)
74VHC123A (Dual Retriggerable Monostable Multivibrator)
74LVC08A (Quad 2-input AND gate)
74HC374 (Octal D-Type Flip-Flop)
74LVC244A (Octal buffer/line driver)
And lastly an Atmel ATF16V8B PLD
Conexant Network Processor SoC
Based on an embedded 75MHZ ARM7TDMI RISC CPU with 5x 10/100 ethernet PHYs, 16Mbit flash support, 128Mbit SDRAM support, UART, etc. Running from a 25 MHz crystal.
CX84200
TMC 16Mbit SDRAM
TM50S116T-7G
Hynix 8Mbit Flash
HY29LV800TT-70
And that’s all.
