Notes for CMOS Devices

1. Precaution against ESD for semiconductors

Strong electric field, when exposed to a MOS device, can cause

destruction of the gate oxide and ultimately degrade the device operation.

Steps must be taken to stop generation of static electricity as much as

possible, and quickly dissipate it once, when it has occurred.

Environmental control must be adequate. When it is dry, humidifier should

be used. It is recommended to avoid using insulators that easily build static

electricity. Semiconductor devices must be stored and transported in an

anti-static container, static shielding bag or conductive material. All test

and measurement tools including work bench and floor should be

grounded. The operator should be grounded using wrist strap.

Semiconductor devices must not be touched with bare hands. Similar

precautions need to be taken for PW boards with semiconductor devices

on it.

2. Handling of unused input pins for CMOS

No connection for CMOS device inputs can be cause of malfunction. If no

connection is provided to the input pins, it is possible that an internal input

level may be generated due to noise, etc., hence causing malfunction.

CMOS devices behave differently than Bipolar or NMOS devices. Input

levels of CMOS devices must be fixed high or low by using a pull-up or pull-

down circuitry. Each unused pin should be connected to VDD or GND with

a resistor, if it is considered to have a possibility of being an output pin. All

handling related to the unused pins must be judged device by device and

related specifications governing the devices.

3. Status before initialization of MOS devices

Power-on does not necessarily define initial status of MOS device.

Production process of MOS does not define the initial operation status of

the device. Immediately after the power source is turned ON, the devices

with reset function have not yet been initialized. Hence, power-on does not

guarantee out-pin levels, I/O settings or contents of registers. Device is not

initialized until the reset signal is received. Reset operation must be

executed immediately after power-on for devices having reset function.

Preface

Readers This manual is intended for users who want to understand the functions of the

concerned microcontrollers.

Purpose This manual presents the hardware manual for the concerned microcontrollers.

Organization This system specification describes the following sections:

• Pin function

• CPU function

• Internal peripheral function

Module instances These microcontrollers may contain several instances of a dedicated module.

In general the different instances of such modules are identified by the index

“n”, where “n” counts from 0 to the number of instances minus one.

Legend Symbols and notation are used as follows:

• Weight in data notation: Left is high order column, right is low order

column

• Active low notation: xxx (pin or signal name is over-scored) or

/xxx (slash before signal name)

• Memory map address: High order at high stage and low order at low

stage

Note Additional remark or tip

Caution Item deserving extra attention

Numeric notation • Binary: xxxx or xxxB

• Decimal: xxxx

• Hexadecimal: xxxxHor 0x xxxx

Prefixes representing powers of 2 (address space, memory capacity):

•K(Kilo): 2

10 = 1024

• M (Mega): 220 = 10242= 1,048,576

•G(Giga): 2

30 = 10243= 1,073,741,824

Diagrams Block diagrams do not necessarily show the exact wiring in hardware but the

functional structure.

Timing diagrams are for functional explanation purposes only, without any

relevance to the real hardware implementation.
