The SST89E516RD2-40-I-NJE from SST (Microchip) is a high-speed 8051-compatible MCU with 64KB SuperFlash, 1KB RAM, and in-application programming in PLCC-44.

The SST89E516RD2-40-I-NJE is an 8051-compatible microcontroller from Microchip (formerly Silicon Storage Technology) in PLCC-44, running at 40MHz with 64KB SuperFlash EEPROM and 1024 bytes of SRAM. The key feature is the dual-bank Flash architecture: 64KB is split into a primary bank (48KB at 0x0000-0xBFFF) and a secondary bank (8KB at 0xC000-0xDFFF). The secondary bank is read-protected and can contain a bootloader that provides IAP (In-Application Programming): the bootloader can erase and reprogram the primary bank via UART, SPI, or I2C without any external programmer. The SuperFlash technology uses a split-gate cell that provides 100,000 write/erase cycles (10x more than standard Flash) and 100-year data retention. The device includes two UARTs (UART0 on P3.0/P3.1, UART1 on P4.2/P4.3), three 16-bit timers (Timer0/1/2), a PCA (Programmable Counter Array) with 5 modules supporting capture, compare, PWM, and watchdog, and an SPI port (P1.5-P1.7). The 8051 core executes one instruction per 12 clock cycles (standard 8051 timing) or per 6 clock cycles (at 40MHz, equivalent to 80MHz standard 8051). The -40 suffix specifies 40MHz operation. The -I suffix specifies industrial temperature (-40C to +85C). The -NJE suffix specifies PLCC-44, lead-free. The device is popular in legacy industrial designs, bootloader-based firmware updates, and applications requiring high endurance Flash.
