GENERAL DESCRIPTION

NY4P 시리즈는 강력한 사운드 프로세서가 내장된 4bit 마이크로 컨트롤러이며, EPROM 기반의 OTP(One Time Programmable) 제품과 MaskROM 기반의 제품으로 나뉘어 집니다.

이 시리즈는 44.1kHz까지의 광범위한 샘플링 속도를 지원하는 고품질의 ADPCM 음성 합성 알고리즘 및 노이즈 필터가 내장되어있어 뛰어난 품질의 음성(Voice)을 재생할 수 있습니다.

이 시리즈는 원가절감을 위하여 외부 앰프를 대신하는 내장된 고품질의 1채널 PWM 다이렉트 드라이브 출력이 있으며, +/- 0.5 % 정확도의 내부 발진기가 있어 외부에 별도의 Rosc를 사용하지 않아도 됩니다.

이시리즈는 슬립 모드의 사용으로 사용자가 제품을 사용하지 않을 때 전력 손실을 최소화할 수 있어 배터리를 이용한 휴대용 기기로 동작 시 오랜 수명을 보장할 수 있습니다.

Features

Wide operating voltage range: 2.0V to 5.5V. (Same as MaskROM products)
4-bit RISC type micro-controller with 44 instructions.
96x4-bit RAM, divided into 2 pages.
1MHz instruction frequency.
HALT mode to save power, less than 1uA standby current.
Precisely embedded oscillator with build-in resistor Rosc (+/- 0.5%).
Low voltage reset (LVR=1.8V), watch-dog reset and I/O port reset are all supported to protect the system.
Maximum 8 flexible I/Os with optional function: floating, pull-high, strong / weak pull-high, Reset input, IR carrier output. I/O’s direction is controlled by registers. For the output port, users can select the normal Drive current output or large Sink current output to directly drive high brightness LED.
Infrared output: optional IR carrier frequency and optional data high/low IR output supported.
New high fidelity ADPCM speech synthesis algorithm.
Built-in noise filter for less background noise at lower volume especially.
One 9-bit hardware PWM output.
Support large PWM current output. (Only for NY4B series. NY4A don’t provide this function.)
Mute mode speech algorithm to save ROM size.
Quick-IO control supported.
A unique fast writing mode is provided to speed up OTP writing time.
A special ICP (In Circuit Programming) writing function is supported for user to fabricate PCBA in advance.
Programmable code protection is provided. (When the Security-Bit is burnt down, data can’t be read.)
Various shipping type for different application requirement.
