mb91f155a/mb91155/mb91154 15 n n n n handling devices 1. preventing latchup in cmos ics, applying voltage higher than v cc or lower than v ss to input/output pin or applying voltage over rating across v cc and v ss may cause latchup. this phenomenon rapidly increases the power supply current, which may result in thermal breakdown of the device. make sure to prevent the voltage from exceeding the maximum rating. 2. treatment of pins ? treatment of unused pins unused pins left open may cause malfunctions. make sure to connect them to pull-up or pull-down resistors. ? treatment of open pins be sure to use open pins in open state. ? treatment of output pins shortcircuiting an output pin with the power supply or with another output pin or connecting a large-capacity load may causes a flow of large current. if this conditions continues for a lengthy period of time, the device deteriorates. take great care not to exceed the absolute maximum ratings. ? mode pins ( md0 - md2 ) these pins should be used directly connected to either v cc or v ss . in order to prevent noise from causing accidental entry into test mode, keep the pattern length as short as possible between each mode pin and v cc or v ss on the board and connect them with low impedance. ? power supply pins when there are several v cc and v ss pins, each of them is equipotentially connected to its counterpart inside of the device, minimizing the risk of malfunctions such as latch up. to further reduce the risk of malfunctions, to prevent emi radiation, to prevent strobe signal malfunction resulting from creeping-up of ground level and to observe the total output current standard, connect all v cc and v ss pins to the power supply or gnd. it is preferred to connect v cc and v ss of mb91f155/mb91154 to power supply with minimal impedance possible. it is also recommended to connect a ceramic capacitor as a bypass capacitor of about 0.1 m f between v cc and v ss at a position as close as possible to mb91f155/mb91154. ? crystal oscillator circuit noises around x0, x1, x0a, and x1a pins may cause malfunctions of mb91f155/mb91154. in designing the pc board, layout x0, x1 (x0a, x1a) and crystal oscillator (or ceramic oscillator) and bypass capacitor for grounding as close as possible. it is strongly recommended to design pc board so that x0, x1, x0a, and x1a pins are surrounded by grounding area for stable operation. the mb91f155a, mb91155 and mb91154 devices do not contain a feedback resistor. to use the clock function, you need to connect an external resistor. 3. precautions ? external reset input it takes at least 5 machine cycle to input l level to the rst pin and to ensure inner reset operation properly. ? external clocks when using an external clock, normally, a clock of which the phase is opposite to that of x0 must be supplied to the x0 and x1 pins simultaneously. however, when using the clock along with stop (oscillation stopped) x0a x1a mb91f155a/mb91155/mb91154
mb91f155a/mb91155/mb91154 16 mode, the x1 pin stops when h is input in stop mode. to prevent one output from competing against another, an external resistor of about 1 k w should be provided. the following figure shows an example usage of an external clock. figure 2.1 an example usage of an external clock 4. care during powering up ? when powering up when turning on the power supply, never fail to start from setting the rst pin to l level. and after the power supply voltage goes to v cc level, at least after ensuring the time for 5 machine cycle, then set to h level. ? source oscillation input at turning on the power supply, never fail to input the clock before cancellation of the oscillation stabilizing waiting. ? power on resetting when powering up or when turning the power back on after the supply voltage drops below the operation assurance range, be sure to reset the power. ? power on sequence turn on the power in the order of v cc , av cc and avrh. the power should be disconnected in inverse order. ? even when an ad converter is not in use , connect av cc to the v cc level and av ss to the v ss level. ? even when a da converter is not in use , connect davc to the v cc level and davs to the v ss level. 5. when the clock function (calendar macro) is not in use not using the clock function, the clock oscillation pin must be configured as shown below. x0 x1 mb91f155a/mb91155/mb91154 x0a x1a mb91f155a/mb91155/mb91154 open this product type does not allow the clock crystal oscillator to be stopped with software.

mb91f155a/mb91155/mb91154 25 [precautions when writing to the modr] before writing to the modr, be sure to set amd0 through 5 and determine the bus width in each cs (chip select) area. the modr does not have bus width setting bits. the bus width value set with mode pins md2 through 0 is enabled before writing to the modr and the bus width value set with bw1 and 0 of amd0 through 5 is enabled after writing to the modr. for example, the external reset vector is normally executed with area 0 (the area where cs0 is active) and the bus width at that time is determined by pins md 2 through 0. suppose that the bus width is set to 32 or 16 bits in md2 though 0 but no value is specified in amd 0. if the modr is written in this state, area 0 then switches to 8-bit bus mode and operates the bus since the initial bus width in amd0 is set to 8 bits. this causes a malfunction. in order to prevent this type of problem, amd0 through 5 must always be set before writing to the modr. writing to the modr. amd0 to amd5 bw1, 0 designated bus width : md2,1,0 rst (reset)
