|

Linksys PAP2 two-port analog telephone adapter
|
||||
|
||||
ESS Visba 3 ES3890F @ 27MHz (CPU/MCU)
|
||||
Realtek RTL8019AS (NIC)
|
||||
ICSI IC41LV16100S-50KG (2MB RAM)
|
||||
SST39VF080-70-4C-EI (1MB flash ROM)
|
||||
2x Silicon Labs Si3210-KT (line interfaces)
|
||||
|
||||
Four of the five LEDs are controlled by ES3890F GPIOs
|
||||
Power LEDs are connected to AUX1[4] and AUX1[5] (pin 112 and 113)
|
||||
Phone 1 LED is connected to AUX1[6] (pin 114)
|
||||
Phone 2 LED is connected to AUX1[7] (pin 115)
|
||||
Ethernet LED is connected to RTL8019AS somehow
|
||||
|
||||
RTL8019AS pin 65 is tied to VDD to disable PnP
|
||||
RTL8019AS pin 96 is tied to ground to share the flash ROM's 8-bit data bus
|
||||
RTL8019AS registers are selected when ES3890F pin 19 (/CS1) is low
|
||||
It looks like the RTL8019AS EEPROM pins are connected to ES3890F AUX2[0-3]?
|
||||
|
||||
|
||||
There are several ATAs based on essentially the same hardware:
|
||||
|
||||
Sipura SPA-2000
|
||||
Sipura SPA-1000
|
||||
Sipura SPA-3000 (ES3890F, RTL8019AS, 2MB RAM, 1MB flash, unknown line interfaces)
|
||||
Sipura SPA-1001 (ES3890F, RTL8019AS, 2MB RAM, 1MB flash, 1x Si3210)
|
||||
Sipura SPA-2100 (Sipura SIP316F @ 27MHz, 2x RTL8019AS, 8MB RAM, 2MB flash, unknown line interfaces)
|
||||
Sipura SPA-2002
|
||||
Linksys PAP2T (ES3890F, RTL8019AS, 2MB RAM, 1MB flash, 2x Si3215)
|
||||
Linksys SPA2102?
|
||||
|
||||
There are also ATAs with similar names but probably very different hardware:
|
||||
|
||||
Linksys PAP2 V2
|
||||
Cisco SPA112
|
||||
Cisco SPA122
