AS8218 / AS8228

Highly Integrated Single Phase 2-Current Energy

Metering Integrated Circuits with Microcontroller, RTC,

Programmable Multi-Purpose I/Os and LCD Driver

DATA SHEET

The AS8218 and AS8228 ICs offer the following

options:

1. Key Features

AS8218: 20 x 4 segment LCDD

9 x multi-purpose I/O (MPIO)

AS8228: 24 x 4 segment LCDD

12 x multi-purpose I/O (MPIO)

Precision single-phase, one or two current input

energy measurement front-end including Sigma-

Delta modulators for A/D-conversion and digital

signal processor (DSP).

Low current consumption of 5mA, depending on

MCU activity.

2. General Description

Digital phase correction and selectable gain on

both current channels for use with two current

transformers (CT) or one CT and one shunt.

The AS8218 / AS8228 are highly integrated CMOS

single-phase energy metering devices for fully

electronic LCD meter systems. The AS8218 /

AS8228 have been designed to ensure the meters

full compliance with the international Standards

IEC62052 and ANSI.

Power-supply monitor (PSM) for power-on reset

and reset when the supply voltage falls below a

defined threshold.

The AS8218 / AS8228 ICs include all the functions

required for conventional 1 current or 2-current

anti-tamper meters. The functions include precision

energy measurement, an 8-bit microcontroller unit

(MCU), an on-chip Liquid Crystal Display driver

(LCDD), programmable multi-purpose

Inputs/Outputs (MPIO), a real time clock/calendar

(RTC) for complex tariff functions such as time-of-

use or maximum demand billing and a Serial

Peripheral Interface (SPI) for reading data from and

writing data to an external non-volatile memory

(EEPROM).

Customer programmable 8-bit 8051 compatible

microcontroller (MCU).

Programmable MCU clock with optional low

power operating conditions.

2 x Universal Asynchronous Receiver /

Transmitters (UART) for external

communications such as programme download

and debugging.

Programmable watchdog timer (WDT) and

external system reset pin.

Real-time clock/calendar (RTC) with on-chip

digital calibration and separate battery supply

pin.

The AS8218 / AS8228 ICs have a dedicated energy

measurement front-end, which includes an analog

front-end and programmable Digital Signal

Processor (DSP) from which active energy, mains

voltage and mains current are provided. Reactive

and apparent energy can also be calculated.

On-chip voltage reference (VREF) with small

temperature coefficient.

Low power 3.0 – 4.0MHz crystal oscillator.

The on-chip 8-bit 8051 compatible microcontroller

is freely programmable and provides user access to

the various functional blocks. The dedicated

Universal Asynchronous Receiver / Transmitter

(UART1) in the System Control block provides

access to various system functions and blocks. A

second UART (UART2) is also provided, which may

for example be used for debugging. The on-chip

memory includes 24kByte program memory and

1kByte data memory. The meter system designer

can select the size of the external EEPROM

memory from 1kByte to 32kByte (in binary steps).

SPI compatible interface for external EEPROM

memory.

Standard on-chip LCD driver (LCDD) interface.

Programmable multi-purpose I/Os (MPIO) with

selectable data direction, pull-up or pull-down

resistors and drive strength.

Mains current lead/lag status indication for

reactive energy measurement.

Low power battery operating mode for meter

reading when Mains voltage is not present.
