AV2132 Datasheet | Apuls Intergrated Circuits

Features y Operating voltage: 2.4V~5.0V y One single-key can implement play-all, play-next and random function. Maximum play count is 32. y 4-column inputs and 3-row outputs can implement 4x4-matrix function. y Each input can implement looping function. y Single-key and 4-column inputs can be last-key priority for stand-alone input or first-key priority. y Each input trigger can select trigger mode: (For OKY, TG0, TG1, TG2, TG3) Edge/Level, Hold/Unhold, Retrigger/Irretrigger. y Each input trigger can select its own debounce time: Fast debounce: < 200us; Slow debounce: ~16ms (S.R.=6.0k Hz) y Support bouncing trigger solution for retrigger application. (Second trigger force to retrigger and slow debounce.) y Maximum table entries are 460- 8. y Word count is only limited by ROM capacity. y 4 output ports for Status or Led application: Ϋʳ OP_A Status: Busy_high ,DC_low, Stop_high,DC_high LED: +Fast,+Slow, Dyn(7/10), Off Ϋʳ OP_B Status: Busy_high, DC_low, Stop_high, DC_high LED: -Fast, -Slow, Dyn(9/10), On Ϋʳ OP_C Status: Busy_high, DC_low, Busy_low, DC_high LED: +Fast, +Slow, On, Off OP_D Status0: Busy_high, DC_low Status1: Busy_low, DC_high y Each output can specify its initial state (High or Low) y Outputs can be set as constant current regardless of the supply voltage varied. y Two PWM playing ports. Drive speaker or buzzer directly (For tone only). y One DAC playing port, together with external bipolar to drive speaker. Ramp up/down is automatic. y For DAC, AVXX32E-B series supports 8 levels of current control to offer flexible choises of corresponding BJT. y Four-level volume control is provided for DAC or PWM output. y Eight-pitch control is provided. y Voice length: 21, 32, 43, 65 and 87 seconds. (ROM capacity : 131072- 5, 196608- 5, 262144- 5, 393216- 5 and 524288- 5 bits) y Voice algorithm: 5-bits LOG_PCM y External resister or built-in resister for system frequency by bonding option on the same pad. y Sixteen default sampling frequencies are...
