Data Sheet February 25, 2011 Features Form, Fit, and Function Compatible with the Intel 82510 Packaging options available: 28-Pin Plastic (PDIP) or, 28-Lead Plastic Leaded Chip Carrier (PLCC), Leaded or RoHS packages available (see Figure 1, Package Pinout) Asynchronous Serial Channel Operation Separate Transmit and Receive FIFOs with Programmable Threshold Programmable Baud Rate Generators up to 288K Baud Special Protocol Features – Control Character Recognition – Auto Echo and Loopback Modes – 9-Bit Protocol Support – 5 to 9 Bit Character Format The IA82510 is a "plug-and-play" drop-in replacement for the original IC. Innovasic produces replacement ICs using its MILES™, 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. MILES™ captures the design of a clone so it can be produced even as silicon technology advances. MILES™ 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. ® IA211001219-05 UNCONTROLLED WHEN PRINTED OR COPIED Page 6 of 25 http://www.Innovasic.com Customer Support: 1-888-824-4184 IA82510 Asynchronous Serial Controller Data Sheet February 25, 2011 D7 D6 D5 D4 D3 D2 D1 (4) (3) (2) (1) (28) (27) (26) D4 (1) (28) D3 D5 (2) (27) D2 D6 (3) (26) D1 D7 (4) (25) D0 INT (5) (24) A2 INT (5) (25) D0 (23) A1 TXD (6) (24) A2 (22) A0 VSS (7) (23) A1 (22) A0 X1 or CLK (9) (20) RDn X1 or CLK (9) SCLK or RIn VDD (10) (19) WRn DSRn or TA or OUT0n (11) (18) CSn DCDn or ICLK or OUT1n (12) (17) RESET RXD (13) (16) RTSn CTSn (14) (15) DSRn or TA or OUT0n IA82510 28-Pin PLCC (21) VDD (10) (20) RDn (11) (19) WRn (12) (13) (14) (15) (16) (17) (18) DTRn or TB DCDn or ICLK or OUT1n SCLK or RIn (21) (8) CSn (8) X2 or OUT2n RESET X2 or OUT2n 28-Pin PDIP RTSn (7) DTRn or TB VSS IA82510 RXD (6) CTSn TXD Figure 1.

Data Sheet February 25, 2011 Description The IA82510 is an asynchronous serial controller that provides a CPU interface to one transmit and one receive channel. It is Form, Fit, and Function compatible with the Intel 82510. Configuration registers are used to control the serial channel, interrupts, and modes of operation. The CPU controls this device via address and data lines with read/write control. The CPU also uses this interface to read and write data to receive and transmit data through the serial channel. FIFOs and various serial modes can be used to help off-load the CPU from transmitting and receiving data. An interrupt line provides an indication to the CPU that the device requires servicing. The device can be configured for 8250A/16450 compatibility. See Figure 2, Functional Block Diagram. ® IA211001219-05 UNCONTROLLED WHEN PRINTED OR COPIED Page 8 of 25 http://www.Innovasic.com Customer Support: 1-888-824-4184 IA82510 Asynchronous Serial Controller Data Sheet February 25, 2011 IA82510 A(2:0) D(7:0) RDn WRn CSn TRANSMITTER TXD RECEIVER RXD BUS INTERFACE (Reset Logic, Registers, Interrupt Generation, INT RESET CTSn RTSn TIMING (Baud Rate Generators A & B, Clocking CONFIG., STATUS, RXDATA TXDATA PIN CONFIGURATION DSRn or TA or OUT0n DCDn or ICLK or OUT1n DTRn or TB MODEM X1 or CLK X2 or OUT2n SCLK or RIn Figure 2.

Functional Overview 3.1 Transmitter Data Sheet February 25, 2011 The Transmit function consists of a 4 11 bit FIFO, and a Transmit Engine. The 4 11 FIFO is configurable as any depth between one and four words inclusive. The transmit engine is responsible for reading the data out of the FIFO and placing it in the proper order on the TXD pin. The transmit engine is highly configurable to be compatible with numerous formats, including 16450 and 8250 modes of communication. Transmit Communication parameters that can be programmed include: Parity modes Stop Bits Character Length FIFO Depth Clocking Options RTS and CTS modes For more details, see Section 3.4, Register Description. 3.2 Receiver The Receiver function consists of a 4 11 configurable FIFO and a Receive Engine. The receive engine is responsible for sampling the data on the RXD input pin, formatting the data, and placing the data in the FIFO. The receive engine is highly configurable with parameters that include: Parity modes Stop Bits Character Length FIFO Depth Clocking Options Address Matching Options Control Character Detection RTS and CTS modes For more details, see Section 3.4, Register Description. 3.3 Bus Interface The Bus Interface is a simple interface that allows a micro-processor or micro-controller to read and write the IA82510 Registers. It consists of the following I/O lines: ® IA211001219-05 UNCONTROLLED WHEN PRINTED OR COPIED Page 10 of 25 http://www Cus IA82510 Asynchronous Serial Controller A0, A1, A2: D0-D7: RDn: WRn: CSn: INT: RESET: 3.4 Data Sheet February 25, 2011 3 Bit Address 8 Bit Data Active Low Read Enable Active Low Write Enable Active Low Chip Select Interrupt Output Chip Reset Register Description Table 1 presents the register summary.
