Core (CPU) type |
ABOV's 8 bit MCUs can be classified by it's core.
And an operation speed is depand on it's core.
it can be arranged by speed like this:,
High Speed 8051 > RISC > 800, Standard 8051
800 type MCU branch out various device which qualified for many years.
To meet the requirement of market which wants high speed MCU,
We are making rather fast high speed MCU(high speed 8051, RISC).

Memory size and type |
ABOV’s General-Purpose MCU has program-code and data memory internally.
We divide off naming like this,
COMBI / FLASH / OTP / MASK MCU.
| - COMBI | : |
It has FLASH memory as program code and EEPROM as data backup memory. |
| - FLASH | : |
It has FLASH memory only as program code. |
| - OTP | : |
It has EPROM as code momory. But it is packaged whitout window, Then it can not be reused by ultraviolet eresing. OTP means 'One Time Programming'. |
| - MASK | : |
It has MASK rom as code memory. It can not change program code after manufacturing.
It is used for cost down in massproduction. |

Package & I/O pins |
According to the MCU and method to use, an input and output port which the utility is possible comes to be different little by little. For example, when we use an utility which we are contained internally.We can use the list of port for this to an input and output list of port. Also when we use a Reset(Power On Reset) circuit which is contained internally. We can use the list of port for this to an input and output(or only input- different according to the MCU) list of port.
The number of input and output list of port which the homepage is marked at the manual is the number of a ( maximum ) input and output list of port which the utility is possible used. When the practical use did such facility all.

Reset (POR, BOR) |
We use the Reset facility following which is contained internally, we may not organize the Reset circuit at the outside. And we can use the list of port for the Reset to an input and output purpose.
| - POR(Power On Reset) | : |
The facility which the Reset the power supply operates at the view to become supply. |
- BOR(Brown Out Reset)
/ BOD(Brown Out Detect Reset) | : |
The facility which the Reset operates if the power supply goes down to a schedule level less.
We are used to prevent the problem which the power supply happens unstable power.
|
|
|
Internal OSC
|
|
We say to be containing the Internal OSC internally at the MCU inside.
The circuit comes to be simple.And there is the advantage for this which can use the list of port to the input and output.
Because We may not organize an eruption circuit at the outside if we use such inside OSC.
|
|
Low Power Consumtion
|
|
We offer a Low Power Mode which greater part of an ABOV’s 8bit MCU calls STOP MODE.
The good development essential facility which this operates to the Battery.
It can operate when a schedule hour interval or specific interrupt happened. According to Type of MCU, we offer a Sleep Mode.
(We are similar with the STOP MODE. But we operate the timer continuously.
And we have the difference to operate by all interrupt.)
|
|
Etc ( ADC, PWM, Timer, Uart, SIO )
|
|
These are general MCU facilities. Please distinguish well because we are showing the difference little by little in the cardinality and number of bit.
