Macronix NBitTM Memory Family
32M-BIT [x 1] CMOS SERIAL eLiteFlashTM MEMORY
FEATURES
GENERAL
• Serial Peripheral Interface (SPI) compatible -- Mode 0
and Mode 3
• 33,554,432 x 1 bit structure
• 64 Equal Sectors with 64K byte each
- Any sector can be erased
• Single Power Supply Operation
- 2.7 to 3.6 volt for read, erase, and program operations
• Latch-up protected to 100mA from -1V to Vcc +1V
• Low Vcc write inhibit is from 1.5V to 2.5V
PERFORMANCE
• High Performance
- Fast access time: 50MHz serial clock (30pF + 1TTL
Load)
- Fast program time: 3ms/page (typical, 256-byte per
page)
- Fast erase time: 1s/sector (typical, 64K-byte per
sector) and 64s/chip (typical)
- Acceleration mode:
- Program time: 2.4ms/page (typical)
- Erase time: 0.8s/sector (typical) and 51s/chip
(typical)
• Low Power Consumption
- Low active read current: 30mA (max.) at 50MHz
- Low active programming current: 30mA (max.)
- Low active erase current: 38mA (max.)
- Low standby current: 50uA (max.)
- Deep power-down mode 1uA (typical)
• Minimum 10K erase/program cycle for array
• Minimum 100K erase/program cycle for additional 4Kb
SOFTWARE FEATURES
• Input Data Format
- 1-byte Command code
• Auto Erase and Auto Program Algorithm
- Automatically erases and verifies data at selected
sector
- Automatically programs and verifies data at selected
page by an internal algorithm that automatically times
the program pulse widths (Any page to be programed
should have page in the erased state first)
• Status Register Feature
• Electronic Identification
- JEDEC 2-byte Device ID
- RES command, 1-byte Device ID
- REMS command, ADD=00H will output the
manufacturer's ID first and ADD=01H will output device
ID first
• Additional 4Kb sector independent from main memory
for parameter storage to eliminate EEPROM from
system
HARDWARE FEATURES
• SCLK Input
- Serial clock input
• SI Input
- Serial Data Input
• SO/PO7
- Serial Data Output or Parallel mode Data output/input
• WP#/ACC Pin
- Hardware write protection and Program/erase accel-
eration
• HOLD# pin
- pause the chip without disselecting the chip (not for
parallel mode, please connect HOLD# pin to VCC dur-
ing parallel mode)
• PO0~PO6
- for parallel mode data output/input
• PACKAGE
- 16-pin SOP (300mil)
- 8-land SON (8x6mm)
- All Pb-free devices are RoHS Compliant

DATA PROTECTION
The MX25L3205A are designed to offer protection against
accidental erasure or programming caused by spurious
system level signals that may exist during power
transition. During power up the device automatically resets
the state machine in the Read mode. In addition, with its
control register architecture, alteration of the memory
contents only occurs after successful completion of
specific command sequences. The device also
incorporates several features to prevent inadvertent write
cycles resulting from VCC power-up and power-down
transition or system noise.
• Power-on reset and tPUW: to avoid sudden power
switch by system power supply transition, the power-
on reset and tPUW (internal timer) may protect the
Flash.
• Valid command length checking: The command length
will be checked whether it is at byte base and com-
pleted on byte boundary.
• Write Enable (WREN) command: WREN command is
required to set the Write Enable Latch bit (WEL) before
other command to change data. The WEL bit will return
to reset stage under following situation:
- Power-up
- Write Disable (WRDI) command completion
- Write Status Register (WRSR) command completion
- Page Program (PP) command completion
- Sector Erase (SE) command completion
- Block Erase (BE) command completion
- Chip Erase (CE) command completion
• Software Protection Mode (SPM): by using BP0-BP2
bits to set the part of Flash protected from data change.
• Hardware Protection Mode (HPM): by using WP# going
low to protect the BP0-BP2 bits and SRWD bit from
data change.
• Deep Power Down Mode: By entering deep power down
mode, the flash device also is under protected from
writing all commands except Release from deep power
down mode command (RDP) and Read Electronic
Signature command (RES).
