FLASH EPROM MEMORY
GENERAL DESCRIPTION
The P89C60X2/61X2 Flash memory augments EPROM functionality
with in-circuit electrical erasure and programming. The Flash can be
read and written as bytes. The Chip Erase operation will erase the
entire program memory. The Block Erase function can erase any
Flash block. In-system programming (ISP) and standard parallel
programming are both available. On-chip erase and write timing
generation contribute to a user friendly programming interface.
The P89C60X2/61X2 Flash reliably stores memory contents even
after 10,000 erase and program cycles. The cell is designed to
optimize the erase and programming mechanisms. In addition, the
combination of advanced tunnel oxide processing and low internal
electric fields for erase and programming operations produces
reliable cycling. The P89C60X2/61X2 uses a +5 V VPP supply to
perform the Program/Erase algorithms (12 V tolerant).
FEATURES
Flash EPROM internal program memory with Block Erase.
Internal 1-kbyte fixed BootROM, containing low-level in-system
programming routines and a default serial loader.
Loader in BootROM allows in-system programming via the serial
port.
Up to 64 kbytes external program memory if the internal program
memory is disabled (EA = 0).
Programming and erase voltage +5 V (+12 V tolerant).
Read/Programming/Erase using ISP:
Byte Programming (8 ms).
Typical erase times:
Block Erase (4 kbytes) in 3 seconds.
Full-chip erase in 15 seconds.
Parallel programming with 87C51 compatible hardware interface
to programmer.
Programmable security for the code in the Flash.
10,000 minimum erase/program cycles for each byte.
10-year minimum data retention.
FLASH PROGRAMMING AND ERASURE
There are two methods of erasing or programming of the Flash
memory that may be used. First, the on-chip ISP boot loader may be
invoked. Second, the Flash may be programmed or erased using
parallel method by using a commercially available EPROM
programmer. The parallel programming method used by these
devices is similar to that used by EPROM 87C51, but it is not
identical, and the commercially available programmer will need to
have support for these devices.
FLASH MEMORY CHARACTERISTICS
Flash User Code Memory Organization
The P89C60X2/61X2 contains 64 kbytes Flash user code program
memory organized into 4-kbyte blocks (see Figure 1).
Boot ROM
When the microcontroller programs its Flash memory during ISP, all
of the low level details are handled by code that is contained in a
1 kbyte BootROM. BootROM operations include: erase block,
program byte, verify byte, program security bit, etc.
Clock Mode
The clock mode feature sets operating frequency to be 1/12 or 1/6 of
the oscillator frequency. The clock mode configuration bit, FX2, is
located in the Security Block (See Table 1). FX2, when programmed,
will override the SFR clock mode bit (X2) in the CKCON register. If
FX2 is erased, then the SFR bit (X2) may be used to select between
6-clock and 12-clock mode.
