Using SST’s patented SuperFlash CMOS semiconductor technology, Microchip(SST) microcontrollers are 8-bit 8052 microcontrollers that are compatible with the 8051 instruction set and fully compatible with the standard 8051 microcontroller Pin-to-PIN. FLASH memory embedded with one/two small sectors (128 bytes/sector), 512Byte/1024 Byte RAM, support double speed, support for power down detection (BOD) and reduced EMI mode, standard UART and high speed SPI serial interface, scalable PCA function module with 5 channels, Dual DPTR data pointer and new P4 port, support IAP online update and online simulation function, with a variety of encryption methods, support low power mode: idle mode and power off mode.

1. Single piece user program space up to 72K.

2. The program and data storage space are complementary, and the remaining FLASH space of the user program can be used as data storage. Enables data storage to exceed 64K.

3. Online simulation function. SOFTICE online simulation function is a good tool for debugging software and hardware. Accelerate the progress of new product design.

4. The strongest and most flexible IAP features:

4.1 IAP is the first concept proposed by SST in the world in 1998.

4.2 User programs can fully reach 64K. Many other MCUS with IAP capabilities cannot reach 64K, because the ISP program takes up part of the 64K space.

4.3 There is no risk of sudden power failure during FLASH erasing and the product cannot run. Other MCUS cannot avoid such problems, and the chip must be removed or sent to the manufacturer for repair.

4.4 The operation of IAP does not affect the execution of other tasks of the product, and other MCUS cannot be avoided. For example, in the LED display, if the IAP operation is performed, other MCUS will appear display pause, making people feel that there is a problem with the product. SST MCUS can avoid this problem.

4.4 The protocol of IAP program is completely determined by the customer, and other MCUS are fixed ISP download programs of the manufacturer, which are easy to cause unsafe factors such as user program code leakage, and are not suitable for online update of the final product.

5. Save cost for the system, save external EEPROM data memory and voltage monitoring chip.

High performance cost ratio performance:

1. Save system cost: can omit the external EEPROM, voltage monitoring chip, power-on reset circuit (about 3 yuan)

2. Save development cost: The chip can come with SOFTICE online simulation function, which can realize single-step, breakpoint, full-speed simulation, and variable data at a glance. It can save companies developing emulators and developing programmers.

3. Save maintenance costs, improve product quality: online application programming (IAP), can achieve remote upgrade of protocol self-determined, safe and convenient maintenance. It saves the mailing cost of product repair and the cost of air tickets for maintenance business trips.

4. Data storage: non-volatile data storage (can exceed 64K), data is not lost after power failure, and on-chip data storage is more confidential.

5. Flexible application: Embedded two small sectors of FLASH memory, program and data storage space fully complementary use, breaking through the standard 51 microcontroller 64K limit space.

6. High reliability and good stability: SST MCU can often be seen in the circuit control board of foreign high-end cars. The automotive environment is harsh, and a chip with poor reliability can lead to major security risks.

Features：

● FLASH memory embedded with two small sectors (128 bytes/sector), data and program space complementary use. Any space that is not used as a program can be used as data storage.

● Online application programming (IAP), eliminating programmer, protocol self-determined remote upgrade, safe and convenient maintenance.

● Large capacity internal data RAM: 1K bytes of internal RAM, C language programming is more convenient;

● Double DPTR data pointer, table lookup, addressing more convenient;

● Added P4 port (I/O port is no longer tense);

● 5-channel programmable counter array (PCA), pulse width measurement, PWM, serial port expansion, multi-machine custom high-speed communication.

● Enhanced UART serial port (supports frame data error detection and automatic address recognition);

●SPI serial interface;

● High reliability: Built-in voltage monitoring circuit for power failure detection, to prevent CPU misoperation at low voltage, so that the system reliability is higher

● Reduce EMI and EMC functions: prohibit ALE output clock, double speed (6 clock/ machine cycle) to reduce crystal frequency.

SuperFlash® Memory Products

What is SuperFlash?

SuperFlash is an innovative, highly reliable and versatile type of NOR Flash memory invented by Silicon Storage Technology (SST). SuperFlash memory is much more flexible and reliable than competing non-volatile memories. This technology utilizes a split-gate cell architecture which uses a robust thick-oxide process that requires fewer mask steps resulting in a lower-cost nonvolatile memory solution with excellent data retention and higher reliability. 

SuperFlash Advantages

SST memory is widely used in DVD players, set-top boxes, e-books, video games, digital monitors, DVD players, VCRS, laptops, Internet machines, desktop computers, computer monitors, data storage devices, printers, scanners, copiers, fax machines, network cameras, point-of-sale equipment, drawing cards, servers, terminals, workstations and mobile devices Phones and other products.
