GENERAL DESCRIPTION

Offered in 16Mx8bit or 8Mx16bit, the K9F28XXX0C is 128M bit with spare 4M bit capacity. The device is offered in 1.8V or 3.3V Vcc. Its NAND cell provides the most cost-effective solutIon for the solid state mass storage market. A program operation can be performed in typical 200μs on the 528-byte(X8 device) or 264-word(X16 device) page and an erase operation can be performed in typical 2ms on a 16K-byte(X8 device) or 8K-word(X16 device) block. Data in the page can be read out at 50ns cycle time per word. The I/O pins serve as the ports for address and data input/output as well as command input. The on-chip write control automates all program and erase functions including pulse repetition, where required, and internal verification and margining of data. Even the writeintensive systems can take advantage of the K9F28XXX0C’s extended reliability of 100K program/erase cycles by providing ECC(Error Correcting Code) with real time mapping-out algorithm.

The K9F28XXX0C is an optimum solution for large nonvolatile storage applications such as solid state file storage and other portable applications requiring non-volatility.

PIN DESCRIPTION

Pin Name	Pin Function
	DATA INPUTS/OUTPUTS
I/O0 ~ I/O7	The I/O pins are used to input command, address and data, and to output data during read operations. The
(K9F2808X0C)	I/O pins float to high-z when the chip is deselected or when the outputs are disabled.
I/O0 ~ I/O15	I/O8 ~ I/O15 are used only in X16 organization device. Since command input and address input are x8 oper-
(K9F2816X0C)	ation, I/O8 ~ I/O15 are not used to input command & address. I/O8 ~ I/O15 are used only for data input and
	output.

						COMMAND LATCH ENABLE
	CLE					The CLE input controls the activating path for commands sent to the command register. When active high,
						commands are latched into the command register through the I/O ports on the rising edge of the WE signal.
						ADDRESS LATCH ENABLE
	ALE					The ALE input controls the activating path for address to the internal address registers. Addresses are
						latched on the rising edge of WE with ALE high.
						CHIP ENABLE
						The CE input is the device selection control. When the device is in the Busy state, CE high is ignored, and
		CE
						the device does not return to standby mode in program or erase opertion. Regarding CE control during read
						operation, refer to ’Page read’section of Device operation .
						READ ENABLE
		RE				The RE input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid
						tREA after the falling edge of RE which also increments the internal column address counter by one.
						WRITE ENABLE
	WE					The WE input controls writes to the I/O port. Commands, address and data are latched on the rising edge of
						the WE pulse.
						WRITE PROTECT
	WP					The WP pin provides inadvertent write/erase protection during power transitions. The internal high voltage
						generator is reset when the WP pin is active low.
						READY/BUSY OUTPUT
						The R/B output indicates the status of the device operation. When low, it indicates that a program, erase or
	R/B
						random read operation is in process and returns to high state upon completion. It is an open drain output and
						does not float to high-z condition when the chip is deselected or when outputs are disabled.
						OUTPUT BUFFER POWER
	VccQ					VCCQ is the power supply for Output Buffer.
						VccQ is internally connected to Vcc, thus should be biased to Vcc.
	Vcc					POWER
						VCC is the power supply for device.
	Vss					GROUND
	N.C					NO CONNECTION
						Lead is not internally connected.
						GND INPUT FOR ENABLING SPARE AREA
	GND					To do sequential read mode including spare area , connect this input pin to Vss or set to static low state
						or to do sequential read mode excluding spare area , connect this input pin to Vcc or set to static high state.
	DNU					DO NOT USE
						Leave it disconnected.

NOTE : Connect all VCC and VSS pins of each device to common power supply outputs.

Do not leave VCC or VSS disconnected.

PRODUCT INTRODUCTION

The K9F28XXX0C is a 132Mbit(138,412,032 bit) memory organized as 32,768 rows(pages) by 528(X8 device) or 264(X16 device) columns. Spare eight columns are located from column address of 512~527(X8 device) or 256~263(X16 device). A 528-byte(X8 device) or 264-word(X16 device) data register is connected to memory cell arrays accommodating data transfer between the I/O buffers and memory during page read and page program operations. The memory array is made up of 16 cells that are serially connected to form a NAND structure. Each of the 16 cells resides in a different page. A block consists of two NAND structures. A NAND structure consists of 16 cells. Total 16896 NAND cells reside in a block. The array organization is shown in Figure 2-1,2-2. The program and read operations are executed on a page basis, while the erase operation is executed on a block basis. The memory array consists of 1024 separately erasable 16K-Byte(X8 device) or 8K-Word(X16 device) blocks. It indicates that the bit by bit erase operation is prohibited on the K9F28XXX0C.

The K9F28XXX0C has addresses multiplexed into 8 I/Os(X16 device case : lower 8 I/Os). K9F2816X0C allows sixteen bit wide data transport into and out of page registers. This scheme dramatically reduces pin counts while providing high performance and allows systems upgrades to future densities by maintaining consistency in system board design. Command, address and data are all written through I/O’s by bringing WE to low while CE is low. Data is latched on the rising edge of WE. Command Latch Enable(CLE) and Address Latch Enable(ALE) are used to multiplex command and address respectively, via the I/O pins. Some commands require one bus cycle. For example, Reset command, Read command, Status Read command, etc require just one cycle bus. Some other commands like Page Program and Copy-back Program and Block Erase, require two cycles: one cycle for setup and the other cycle for execution. The 16K-byte(X8 device) or 32K-word(X16 device) physical space requires 24 addresses, thereby requiring three cycles for word-level addressing: column address, low row address and high row address, in that order. Page Read and Page Program need the same three address cycles following the required command input. In Block Erase operation, however, only the two row address cycles are used. Device operations are selected by writing specific commands into the command register. Table 1 defines the specific commands of the K9F28XXX0C.

The device includes one block sized OTP(One Time Programmable), which can be used to increase system security or to provide identification capabilities. Detailed information can be obtained by contact with Samsung.

Table 1. COMMAND SETS

Function		1st. Cycle	2nd. Cycle	Acceptable Command during Busy
Read 1		00h/01h(1)	-
Read 2		50h	-
Read ID		90h	-
Reset		FFh	-	O
Page Program		80h	10h
Block Erase		60h	D0h
Read Status		70h	-	O
NOTE: 1. The 00h command defines starting address of the 1st half of registers.
The 01h command defines starting address of the 2nd half of registers.
After data access on	2nd half of register by the 01h command, start pointer is automatically moved to

1st half register(00h) on the next cycle.

Caution : Any undefined command inputs are prohibited except for above command set of Table 1.

NOTE :

1.Minimum DC voltage is -0.6V on input/output pins. During transitions, this level may undershoot to -2.0V for periods <30ns. Maximum DC voltage on input/output pins is VCC,+0.3V which, during transitions, may overshoot to VCC+2.0V for periods <20ns.

2.Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to the conditions as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
