DEVICE MARKING
Due to the size of the package, NanoAmp’s standard
part number is not printed on the top of each device.
Instead, an abbreviated device mark comprised of a
five-digit alphanumeric code is used. The abbreviated
device marks are cross referenced to NanoAmp part

GENERAL DESCRIPTION
The EM28C1604C3FL, a combination of Flash and
SRAM memory, provides a compact, low-power
solution for systems where PCB real estate is at a
premium. The device contains a nonvolatile, electrically
block-erasable (flash), programmable, read-only memory
containing 16,777,216 bits organized as 1,048,576 words
(16 bits).
The device also provides soft protection for blocks by
configuring soft protection registers with dedicated com-
mand sequences. A 128-bit (OTP )one time programmable
register is provided.
The embedded WORD WRITE and BLOCK ERASE
functions are fully automated by an on-chip write state
machine (WSM). The WSM simplifies these operations and
relieves the system processor of secondary tasks. An
on-chip status register, can be used to monitor the WSM
status to determine the progress of a PROGRAM/ERASE
command.
The erase/program suspend functionality allows com-
patibility with existing EEPROM emulation software pack-
ages.
The device takes advantage of a dedicated power
source for the Flash device (F_VCC) and a dedicated
power source for the SRAM device (S_VCC), both at
2.7V–3.3V for optimized power consumption and im-
proved noise immunity. The separate S_VCC pin for the
EM28C1604C3FL
Advance
SRAM provides the data retention capability whenever
required. The data retention S_VCC is specified as low as
1.0V. The device supports two VPP voltages; in-circuit
VPP of 1.65V–3.3V and production compatibility of 12V
±5%. The 12V ±5% VPP is supported for a maximum of 100
cycles and 10 cumulative hours.
The EM28C1604C3FL contains an asynchronous 4Mb
SRAM organized as 256K-words by 16 bits. This device
is fabricated using an advanced CMOS process and high-
speed/ultra-low-power circuit technology.
The EM28C1604C3FL is packaged in a 66-ball FBGA
package with 0.80mm pitch.
