The IA82510 is a "plug-and-play" drop-in replacement for the original IC. innovASIC produces replacement ICs
using its MILESTM, or Managed IC Lifetime Extension System, cloning technology. This technology produces
replacement ICs far more complex than "emulation" while ensuring they are compatible with the original IC.
MILESTM captures the design of a clone so it can be produced even as silicon technology advances. MILESTM
also verifies the clone against the original IC so that even the "undocumented features" are duplicated. This data
sheet documents all necessary engineering information about the IA82510 including functional and I/O
descriptions, electrical characteristics, and applicable timing.

Notes:
1. Does not apply to CLK/X1 pin, when configured as crystal oscillator input (X1).
2. @IOL = 1.92 mA
3. @IOH = 1.92 mA
4. 0< VIN <VCC
5. 0.4V < VOUT < VCC – 0.4V
6. VDD = 5.5V, VIL = 0.7V (max), VIH = VDD – 0.7V (min), Typ. Val = 1.12 mA/MHz (Not
Tested), Ext. 1X CLK, IOL = IOH = 0
7. Freq. = 1 MHz
8. Does not apply to OUT2/X2 pin, when configured as crystal oscillator output (X2).
9. Freq. = 1 MHz, but input clock not running. Static IDD current is exclusive of input/output
drive requirements and is measured with the clocks stopped and all inputs tied to VDD or
VSS, configured to draw minimum current.
10. Applies only during hardware reset for clock configuration options. Strapping current for
logic HIGH.
11. Applies only during hardware reset for clock configuration options. Strapping current for
logic LOW.
12. Inputs (RTSn, DTRn, TB) with Pullups tested @ Vin = 0.0V, VDD = 5.5V

can be altered to the point of confusing the downstream receiver.
Workaround: Change firmware to Manual TX mode to control RTS vs. start of character.
