HT82A832R General Description

The HT82A832R is an 8-bit high performance RISC-like microcontroller designed for USB Phone product applications. There are some features as follows. First is two 16-bit programmable timer/event counters and overflow interrupts. The second is embedded high-performance 16 bit PCM ADC. Then is built-in Digital PGA (Programmable Gain Amplifier). Next is 48kHz/8kHz sampling rate for audio playback controlled by software option. The fifth is embedded High Performance 16 bit audio DAC. The sixth is two hardware implemented Isochronous transfers. The seventh is programmable frequency divider (PFD). The eighth is watchdog timer. The ninth is 16-level subroutine nesting. The last one is low voltage reset function (3.0 V±0.3 V).

What comes next is about the maximum ratings. The supply voltage is from VSS-0.3 to VSS+6.0 V. The input voltage is from VSS-0.3 to VDD+6.0 V. The TA (operating temperature range) is from -40 to +85. The Ts (storage temperature range) is from -55 to 125.

The following is about the DC characteristics. The minimum VIL1 (Input Low Voltage for I/O Ports) is 0 V and the maximum is 0.3VDD V at VDD=5 V. The minimum VIH1 (Input High Voltage for I/O Ports) is 0.7VDD V and the maximum is VDD V at VDD=5 V. The minimum VIL2 (Input Low Voltage (RESET)) is 0 V and the maximum is 0.4VDD V at VDD=5 V. The minimum VIH2 (Input Low Voltage (RESET)) is 0.9VDD V and the maximum is VDD V at VDD=5 V. The typical IOL (I/O Port Sink Current) is 5 mA at VDD=5V, VOL=0.1VDD. The typical IOH (I/O Port Source Current) is -5 mA at VDD=5V, VOH=0.7VDD.
