Handling Devices Strictly Observe Maximum Rated Voltages (Preventing Latch-up) In CMOS IC devices, a condition known as latch-up may occur if voltages higher than VCC or lower than VSS are applied to input or output pins other than medium or high withstand voltage pins, or if the voltage applied between VCC and VSS pins exceeds the rated voltage level. If a latch-up occurs, the power supply current may increase dramatically and may destroy semiconductor elements. When using semiconductor devices, always take sufficient care to avoid exceeding maximum ratings. When the analog system power supply is switched on or off, be careful not to apply the analog power supply (AVCC, AVRH), the analog input voltages and the power supply voltage for the high current output buffer pins (DVCC) in excess of the digital power supply voltage (VCC). Once the digital power supply voltage (VCC) has been disconnected, the analog power supply (AVCC, AVRH) and the power supply voltage for the high current output buffer pins (DVCC) may be turned on in any sequence. Supply Voltage Stabilization Rapid fluctuations in the power supply voltage can cause malfunctions even if the Vcc power supply voltage remains within the warranted operating range. It is recommended that the power supply be stabilized such that ripple fluctuations (P-P value) at commercial frequencies (50 Hz/60 Hz) be limited to within 10 of the standard VCC value, and that transient fluctuations due to power supply switching, etc. be limited to a rate of 0.1 V/ms or less. Precautions when Turning the Power On In order to prevent the built-in step-down circuits from malfunctioning, the time taken for the voltage to rise (0.2 V to 2.7 V) during power-on should be less than 50 s. Handling Unused Pins If unused input pins are left open, they may cause malfunctions or latch-up which may lead to permanent damage to the semiconductor. Unused input pins should therefore be pulled up or pulled down through a resistor of at least 2 k. Unused input/output pins may be set to the output state and left open, or set to the input state and connected to a pull-up or pull-down resistance of 2 k or more. Handling A/D Converter Power Supply Pins Even if the A/D converter is not used, the power supply pins should be connected such as AVCC  VCC, and AVSS  AVRH  VSS. Notes on Using an External Clock Even when an external clock is used, an oscillation stabilization wait time is required following power-on reset or release from sub clock mode or stop mode. Furthermore, only the X0A pin should be driven when an external clock is used, with the X1A pin open as shown in the following diagram. Do not use high-speed oscillation pins (X0 and X1) for external clock input. X0A OPEN X1A CY90920 Series Sample external clock connection Notes on Operating in PLL Clock Mode On this microcontroller, if in case the crystal oscillator breaks off or an external reference clock input stops while the PLL clock mode is selected, a self-oscillator circuit contained in the PLL may continue its operation at its self-running frequency. However, Cypress will not guarantee results of operations if such failure occurs. Crystal Oscillator Circuit Noise around the X0/X1, or X0A/X1A pins may cause this device to operate abnormally. In the interest of stable operation it is strongly recommended that printed circuit artwork places ground bypass capacitors as close as possible to the X0/X1, X0A/X1A and crystal oscillator (or ceramic oscillator) and that oscillator lines do not cross the lines of other circuits. Please ask each crystal maker to evaluate the oscillational characteristics of the crystal and this device.

To reduce unnecessary radiation, prevent malfunctioning of the strobe signal due to the rise of ground level, and observe the standard for total output current, be sure to connect the VCC and VSS pins to the power supply and ground externally. Always connect all of the VCC pins to the same potential and all of the VSS pins to ground as shown in the following diagram. The device will not operate correctly if multiple VCC or VSS pins are connected to different voltages, even if those voltages are within the guaranteed operating ranges. VCC VSS VCC VSS VSS VCC VCC VSS VSS VCC Power supply input pins (Vcc/Vss) In addition, care must be given to connecting the VCC and VSS pins of this device to the current supply source with as low impedance as possible. It is recommended that a 1.0 F bypass capacitor be connected between the VCC and VSS pins as close to the pins as possible. Sequence for Connecting the A/D Converter Power Supply and Analog Inputs The A/D converter power supply (AVCC, AVRH) and analog inputs (AN0 to AN7) must be applied after the digital power supply (VCC) is switched on. When turning the power off, the A/D converter power supply and analog inputs must be disconnected before the digital power supply is switched off (VCC). Ensure that AVRH does not exceed AVcc during either power-on or power-off. Even when pins which double as analog input pins are used as input ports, be sure that the input voltage does not exceed AVCC (turning on/off the analog and digital power supplies simultaneously is acceptable). Handling the Power Supply for High-current Output Buffer Pins (DVCC, DVSS) ■ Flash memory products and MASK ROM products (CY90F922NC/F922NCS/922NCS/F923NC/F923NCS/F924NC/F924NCS) In the Flash memory products and MASK ROM products, the power supply for the high-current output buffer pins (DVCC, DVSS) is isolated from the digital power supply (VCC). Therefore, DVcc can therefore be set to a higher voltage than Vcc. If the power supply for the high-current output buffer pins (DVCC, DVSS) is supplied before the digital power supply (VCC), however, care needs to be taken because it is possible that the port 7 or port 8 stepping motor outputs may momentarily output an “H” or “L” level. In order to prevent this, connect the digital power supply (VCC) prior to connecting the power supply for the high-current output buffer pins. Even when the high-current output buffer pins are used as general-purpose ports, power should be supplied to the power supply pins for the high-current output buffer pins (DVCC, DVSS). ■ Evaluation product (CY90V920-101/CY90V920-102) In the evaluation products, the power supply for the high-current output buffer pins (DVCC, DVSS) is not isolated from the digital power supply (VCC). Therefore, DVCC must therefore be set to a lower voltage than Vcc. The power supply for the high-current output buffer pins (DVCC, DVSS) must always be applied after the digital power supply (VCC) has been connected, and disconnected before the digital power supply (Vcc) is disconnected (the power supply for the high-current output buffer pins may also be connected and disconnected simultaneously with the digital power supply). Even when the high-current output buffer pins are used as general-purpose ports, power should be supplied to the power supply pins for the high-current output buffer pins (DVCC, DVSS).

Use external components as necessary. Precautions When Not Using a Sub Clock Signal If the X0A and X1A pins are not connected to an oscillator, apply a pull-down resistance to the X0A pin and leave the X1A pin open. Notes on Operating When the External Clock is Stopped The CY90920 series is not guaranteed to operate correctly using the internal oscillator circuit when there is no external oscillator or the external clock input is stopped. Flash Memory Security Function A security bit is located within the Flash memory region. The security function is activated by writing the protection code 01H to the security bit. Do not write the value 01H to this address if you are not using the security function. Please refer to following table for the address of the security bit. Flash Memory Size Address for Security Bit CY90F922NC CY90F922NCS Built-in 2 Mbits Flash Memory FC0001H CY90F923NCS Built-in 3 Mbits Flash Memory F80001H CY90F924NCS Built-in 4 Mbits Flash Memory F80001H Serial Communication In serial communication, reception of wrong data may occur due to noise or other causes. Therefore, design a printed circuit board to prevent noise from occurring. Taking account of the reception of wrong data, detect errors by measures such as adding a checksum to the end of data. If an error is detected, retransmit the data. Characteristic Difference Between Flash Device and MASK ROM Device In the flash device and the MASK ROM device, the electrical characteristic including current consumption, ESD, latch-up, the noise characteristic, and oscillation characteristic, etc. is different according to the difference between the chip layout and the memory structure. Reconfirm the electrical characteristic when the product is replaced by another product of the same series. Document Number: 002-07917 Rev. *A Page 18 of 64 CY90920 Series 6.

Treat this address as the ROM decode area used by the tools. Note: To select models without the ROM mirror function, refer to the “ROM Mirror Function Selection Module” in Hardware Manual. The image of the ROM data in the FF bank appears at the top of the 00 bank, in order to enable efficient use of small C compiler models. The lower 16-bits of the FF bank addresses are allocated to the same addresses as the lower 16-bits of the 00 bank, making it possible to reference tables in ROM without declaring the “far” modifier with the pointers. For example, when an access is made to the address 00C000H, the actual address to be accessed is FFC000H in ROM. Because the size of the FF bank ROM area exceeds 32 Kbytes, it is not possible to view the entire region in the 00 bank image. Therefore because the ROM data from FF8000H to FFFFFFH appears in the image from 008000H to 00FFFFH, it is recommended that ROM data tables be stored in the area from FF8000H to FFFFFFH.

If the external impedance is too high to keep sufficient sampling time, the analog voltage charged to the internal sample and hold capacitor is insufficient, adversely affecting A/D conversion precision. Therefore, to satisfy the A/D conversion precision standard, consider the relationship between the external impedance and minimum sampling time and either adjust the register value and operating frequency or decrease the external impedance so that the sampling time is longer than the minimum value. If the sampling time is still not sufficient, connect a capacitor of about 0.1 F to the analog input pin.
