Chapter 1. Introduction
1.1 General Description
The NY8L IC is a high-performance 8-bit 65C02 micro-controller with LCD driver and sound processor, three
sets of 8-bit timer/counter, 13~32 general I/Os. For LCD driver, it applies for the most common-used LCD
panel and functions as a key strobe for further application.
There are 3 channels that are configured as 1-channel speech and dual-tone melody (by body), and all of
them can be auto-played back simultaneously. Not only high fidelity ADPCM speech synthesis algorithm
built-in, but also wide range sampling rate up to 16KHz@4MHz and different volume level are supported.
Those combinations create remarkable high-quality voice. NY8L provides two kinds of audio outputs with fine
resolution (by body), one is 10-bit current-type D/A converter (DAC) and the other is 9-bit Pulse-Width-
Modulation (PWM).
The NY8L IC provides 4 channels high-precision 8-bit analog-to-digital converter (ADC) (by body), which is
suitable for any analog interface detection and measurement applications.
The CISC MCU architecture is very easy to program and control, various applications can be easily
implemented. Furthermore, in addition to the Slow mode, it offers the Standby mode and Halt mode (or
Sleep mode) to minimize power dissipation.
1.2 Features
Wide operating voltage range: 1.1V ~ 3.6V / 2.0V ~ 5.5V. (by body)
1.1V ~ 3.6V @ System clock ≤ 500KHz (NY8L005A, NY8L010A, NY8L020A).
2.0V ~ 3.6V @ System clock ≤ 4MHz (NY8L005A, NY8L010A, NY8L020A).
2.0V ~ 5.5V @ System clock ≤ 4MHz (NY8L030A, NY8L040A, NY8L050A).
3.0V ~ 5.5V @ System clock ≤ 8MHz (NY8L030A, NY8L040A, NY8L050A).
4KB~128KB ROM (by body), program and voice data share the same ROM space.
64B~320B RAM. (by body)
Dual-clock oscillation: System clock can switch between high oscillation and low oscillation.
High oscillation: IOSC8M/IOSC4M/IOSC2M/IOSC500K.
Low oscillation: IOSC32K/XTAL32K.
Built-in RC oscillation is accurate with +/- 1.5% frequency deviation.
Four kinds of operation mode to reduce system power consumption:
Normal mode, Slow mode, Standby mode and Halt mode.
At Normal mode, CPU clock is software programmable.
1/1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 of high oscillator (FFAOS) frequency.

Electroluminescent (EL) back light driver block supported with various frequency and duty.
Resistance to Frequency Converter (RFC) for the detection of humidity, temperature or other applications.
Low voltage reset (by body), watch-dog reset (by option) and external reset pin (by option) are all
supported to protect the system.
Flexible I/Os maximum with optional function:floating input, pull-low input, CMOS output, open-drain output.
Infrared (IR) output: optional carrier frequency and optional data high/low output supported.
Maximum of 3 channels can play simultaneously (by body); channel0/1 can be assigned as tone,
channel2 can be assigned as speech.
New high fidelity ADPCM speech synthesis algorithm.
High quality direct-drive 9-bit PWM and 10-bit D/A converter audio output. (by body)
8 or 16 steps volume control for audio output.
4 channels high-precision 8-bit analog-to-digital converter (ADC). (by body)
7~8 interrupt modes supported (by body).
