AS1110-BQFR

A S1110 1 General Description The AS1110 is designed to drive up to 16 LEDs through a fast serial interface and features 16 output constant current drivers and an on-chip diagnostic read-back function. The high clock-frequency (up to 50MHz), adjustable output current, and flexible serial interface makes the device perfectly suited for high-volume transmission applications. Output current is adjustable (up to 100mA/channel) using an external resistor (REXT). The serial interface with Schmitt trigger inputs includes an integrated shift register. Additionally, an internal data register stores the currently displayed data. The device features integrated diagnostics for overtemperature, open-LED, and shorted-LED conditions. Integrated registers store global fault status information during load as well as the detailed temperature/openLED/shorted-LED diagnostics results. The AS1110 also features a low-current diagnostic mode to minimize display flicker during fault testing. The AS1110 is available in a 24-pin SSOP and the 28pin QFN (5x5mm) package.

Furthermore, the AS1110 provides diagnostics for detecting open- or shorted-LEDs, as well as over-temperature conditions for LED display systems, especially LED traffic sign applications. The AS1110 contains an 16-bit shift register and an 16-bit data register, which convert serial input data into parallel output format. At AS1110 output stages, sixteen regulated current sinks are designed to provide uniform and constant current with excellent matching between ports for driving LEDs within a wide range of forward voltage variations. External output current is adjustable from 0.5 to 100mA using an external resistor for flexibility in controlling the brightness intensity of LEDs. The AS1110 guarantees to endure 15V maximum at the outputs. The serial interface is capable of operating at a minimum of 30 MHz, satisfying the requirements of high-volume data transmission. Using a multiplexed input/output technique, the AS1110 adds additional functionality to pins SDO, LD and OEN. These pins provide highly useful functions (open- and shorted-LED detection, over-temperature detection), thus reducing pin count. Over-temperature detection will work on-the-run, whereas the open- and shorted-LED detection can be used on-the-run or in low-current diagnostic mode (see page 15). Figure 8.

At each CLK rising edge, the signal present at pin SDI is shifted into the first bit of the internal shift register and the other bits are shifted ahead of the first bit. The MSB is the first bit to be clocked in. In error-detection mode the shift register will latch-in the corresponding error data of temperature-, open-, and short-error register with each falling edge of LD. The 16-bit data register will latch the data of the shift register at each rising edge of LD. This data is then used to drive the current generator output drivers to switch on the corresponding LEDs as OEN goes low.

Error-detection mode is started on the rising edge of LD when OEN is high. The CLK signal must be low when entering error detection mode. Error detection for open- and shorted-LEDs can only be performed for LEDs that are switched on during test time. To switch between error-detection modes clock pulses are needed (see Table 5). Note: To test all LEDs, a test pattern that turns on all LEDs must be input to the AS1110. Global Error Mode Global error mode is entered when error-detection mode is started. Clock pulses during this period are used to select between temperature, open-LED, and shorted-LED tests, as well as low-current diagnostic mode and shutdown mode (see Table 5). In global error mode, an error flag (TFLAG, OFLAG, SFLAG) is delivered to pin SDO if any errors are encountered. Table 5.

Note: For a valid result SDI must be 1 for the first device. www.austriamicrosystems.com Revision 1.04 11 - 24 AS1110 Datasheet - D e t a i l e d D e s c r i p t i o n If there are multiple AS1110s in a chain, the error flag will be gated through all devices. To get a valid result at the end of the chain, a logic 1 must be applied to the SDI input of the first device of the chain. If one device produces an error this error will show up after n*tP(I/O) + tSW(ERROR) at pin SDO of the last device in the chain. This means it is not possible to identify which device in the chain produced the error. Therefore, if a global error occurs, the detailed error report can be run to identify which AS1110, or LED produced the error. Note: When no error has occurred, the detailed error report can be skipped, setting LD and subsequently OEN low. Error Detection Functions Open-LED Detection The AS1110 open-LED detection is based on the comparison between VDS and VTHL. The open LED status is aquired at the rising edge of OEN and stored internally. While detecting open-LEDs the output port must be turned on. Open LED detection can be started with 1 clock pulse during error detection mode while the output port is turned on. Note: LEDs which are turned off at test time cannot be tested and will be shown as a logic 1 in the detailed error report. Table 6. Open LED Detection Modes Output Port State On On Effective Output Point Conditions VDS < VTHL VDS > VTHL Detected Open-LED Error Status Code 0 1 Meaning Open Circuit Normal Shorted-LED The AS1110 shorted-LED detection is based on the comparison between VDS and VTHH. The shortened LED status is aquired at the rising edge of OEN and stored internally. While detecting shorted-LEDs the output port must be turned on. Shorted-LED detection can be started with 2 clock pulses during error detection mode while the output port is turned on. For valid results, the voltage at OUTN0:OUTN15 must be lower then VTHH under low-current diagnostic mode operating conditions. This can be achieved by reducing the VLED voltage or by adding additional diodes, resistors or LED’s. Note: LEDs which are turned off at test time cannot be tested and will be shown as a logic 1 in the detailed error report. Table 7.

The overtemperature status is aquired at the rising edge of OEN and stored internally. Table 8.

At the falling edge of LD, the detailed error report of the selected test is latched into the shift register and can be clocked out with n*16 clock cycles (n is the number of AS1110s in a chain) via pin SDO. At the same time new data can be written into the shift register, which is loaded on the next rising edge of pin LD. This pattern is shown at the output drivers, at the falling edge of OEN. Detailed Temperature Warning Report The detailed temperature warning report can be read out immediately after global error mode has been run. SDI must be 1 for the first device. Bit0 of the 16bit data word represents the temperature flag of the chip. Figure 14.

The detailed error report lists the temperatures for each device in the chain: IC1:[70°] IC2:[85°] IC3:[170°] IC4:[60°] In this case, IC3 is overheated and will generate a global error, and therefore 4*16 clock cycles are needed to write out the detailed temperature warning report, and optionally read in new data. The detailed temperature warning report would look like this: XXXXXXXXXXXXXXX1 XXXXXXXXXXXXXXX1 XXXXXXXXXXXXXXX0 XXXXXXXXXXXXXXX1 The 0 in the detailed temperature warning report indicates that IC3 is the device with the over-temperature condition. Note: In an actual report there are no spaces in the output. www.austriamicrosystems.com Revision 1.04 13 - 24 AS1110 Datasheet - D e t a i l e d D e s c r i p t i o n Detailed Open-LED Error Report The detailed open-LED error report can be read out immediately after global error mode has been run.

Detailed Open-LED Error Report Example Consider a case where three AS1110s are cascaded in one chain. A 1 indicates a LED is on, a 0 indicates a LED is off, and an X indicates an open LED. The open-LED test is only applied to LEDs that are turned on. This test is used with a test pattern where all LEDs are on at test time. IC1:[1111111111111111] IC2:[111XX11111111X11] IC3:[1111111111111111] IC2 has three open LEDs switched on due to input. 3*16 clock cycles are needed to write the entire error code out. The detailed error report would look like this: Input Data: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 LED Status: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Failure Code: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1111111111111111 1 1 1 XX1 1 1 1 1 1 1 1 X1 1 1110011111111011 1111111111111111 1111111111111111 1111111111111111 Comparing this report with the input data indicates that IC2 is the device with two open LEDs at position 4 and 5 and one open LED at position 14. For such a test it is recommended to enter low-current diagnostic mode first (see LowCurrent Diagnostic Mode on page 15) to reduce screen flickering. This test can be used also on-the-fly without using an all 1s test pattern (see Figure 19 on page 17). Note: In an actual report there are no spaces in the output. LEDs turned off during test time cannot be tested and will show a logic 1 in the detailed error report. www.austriamicrosystems.com Revision 1.04 14 - 24 AS1110 Datasheet - D e t a i l e d D e s c r i p t i o n Detailed Shorted-LED Error Report The detailed shorted-LED error report can be read out immediately after global error mode has been run (see Global Error Mode on page 11).

A 1 indicates a LED is on, a 0 indicates a LED is off, and an X indicates a shorted LED. This test is used on-the-fly. IC1:[11111XX111111111] IC2:[1111111111111111] IC3:[X100011111111111] IC1 has two shorted LEDs which are switched on, IC3 has one shorted LED switched off due to input. 3*16 clock cycles are needed to write the entire error code out. The detailed error report would look like this: Input Data: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 LED Status: 1 1 1 1 1 X X 1 1 1 1 1 1 1 1 1 Failure Code: 1 1 1 1 1 0 0 1 1 1 1 1 1 1 1 1 1111111111111111 1111111111111111 1111111111111111 0100011111111111 X1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1111111111111111 Showing IC1 as the device with two shorted LEDs at position 6 and 7, and IC3 with one shorted LED at position 1. The shorted LED at position 1 of IC3 cannot be detected, since LEDs turned off at test time are not tested and will show a logic "1" at the detailed error report. To test all LEDs this test should be run with an all 1s test pattern. For a test with an all on test pattern, low-current diagnostic mode should be entered first to reduce on-screen flickering. Note: In an actual report there are no spaces in the output. LEDs turned off during test time cannot be tested and will show a logic 1 in the detailed error report. Low-Current Diagnostic Mode To run the open- or shorted-LED test, a test pattern must be used that will turn on each LED to be tested. This test pattern will cause a short flicker on the screen while the test is being performed. The low-current diagnostic mode can be initiated prior to running a detailed error report to reduce this on-screen flickering. Note: Normally, displays using such a diagnostic mode require additional cables, resistors, and other components to reduce the current. The AS1110 has this current-reduction capability built-in, thereby minimizing the number of external components required. Low-current diagnostic mode can be initiated via 3 clock pulses during error-detection mode. After the falling edge of LD, a test pattern displaying all 1s can be written to the shift register which will be used for the next error-detection test. www.austriamicrosystems.com Revision 1.04 15 - 24 AS1110 Datasheet - D e t a i l e d D e s c r i p t i o n On the next falling edge of OEN, current is reduced to ILC. With the next rising edge of OEN the current will immediately increase to normal levels and the detailed error report can be read out entering error-detection mode. Figure 17.

Shutdown Mode The AS1110 features a shutdown mode which can be entered via 4 clock pulses during error-detection mode. To enable the shutdown mode a 0 must be placed at SDI after the rising edge of the 3rd clock pulse. To disable shutdown mode a 1 must be placed at SDI after the 3rd clock pulse. The shutdown/wakeup information will be latched through if multiple AS1110 devices are in a chain. At the rising edge of the 4th clock pulse the shutdown bit will be read out and the AS1110 will shutdown or wakeup. Note: In shutdown mode the supply current drops down to PD(MAX) where VDS = VLED - VF. In this case, the lowest possible supply voltage or a voltage reducer (VDROP) should be used. The voltage reducer allows VDS = (VLED -VF) - VDROP. Note: Resistors or zener diodes can be used as a voltage reducer as shown in Figure 23. www.austriamicrosystems.com Revision 1.04 19 - 24 AS1110 Datasheet - A p p l i c a t i o n I n f o r m a t i o n Figure 23.
