General Description
JA21000 is a series of 3 to 340 seconds single chip voice synthesizer IC with RTC which contains a PWM direct drive circuit or AUD output for transistor application. In addition, this chip also provides high sink current port pins, multi external interrupt pins function, and multi oscillator options. JA21000 series offers one of the best cost/performance ratios in the toy or industry for controller. It also supplies high-sink current port pins, multi-external wake-up pins function and multi-oscillator options. The JA21000 series can support 32K crystal oscillator for timer with low operating current. In addition, this JA21000 series family IC leads users into an easy-to use development environment that shorten developer's period and fasten time-to-market. Moreover, fantastic sound effects can be generated by users easily without writing complex programs. This JA21000 series family offers the best cost/performance ratios for toy, consumer, and industry use.

Normal I/O pins in direct mode. For output mode, they are open drain output; For input mode, they are without pull-high resistor. Keyboards scan output in matrix mode. Normal I/O pins in direct mode. For output mode, they are CMOS output; For input mode, they are with pull-high resistor. Keyboards scan input in direct/matrix mode. PB0 PB3 pins are for all series. PB4 PB7 pins are for JA21128 -- JA21340 only. Positive power supply. In RC mode, it connects an external oscillator resistor between OSCI and VDD. As well, the pin can be used as an external clock input. Current type output or PWM type output by mask option. For current type output, it must drive an external transistor and only for JA21018 -- JA21340. For PWM type output, it can drive a speaker directly. (8 ohm 32 ohm) The AUD1 output is provided to JA21018 -- JA21340, and the AUD2 output is provided to JA21064 -- JA21340 only.
